it was great collabing with you!! your TEA laser has excellent output, in fact it's quite nearly ideal for this type of build running in open air.
Hi
Daddy lasew man owo
thanks for checking in man. we were worried. :D
oi cara hello dude
"High voltage and fire really gets my attention" ⚡🔥
Very nice project Jay, got some really cool shots there! You and Drake did a good job.
Big fan sir 🥰🥰🥰
Cool
Hello sir
You're bigger than styropyro yet your comment got less likes, I think you'd fit in better with the hacksmith sense they do a lot of big stuff with pre-built parts while these guys are more about building smaller things from scratch
@@ironicman6731 comments' likes don't matter with channels subs. It's the content of the comment that gets it likes.
Your shirt probably fluoresces because of the detergent. When the companies say "whiter than white" they mean they put florescent dye into the detergent to make them brighter in sunlight.
so we can take detergent and disolve it in water or alcohol to make a dye for the laser and we can get visible laser beam after it goes through it? im not juts talking about inside the cuvette or jar but once it passes should you not get a visible beam?
@@ARCSTREAMS I don't think that'll work since fluorescent material emits light in all directions, not directionally. So the detergent solution would glow, and some UV light that weren't absorbed would pass through, but I don't think you'd be getting dyed laser this way.
@@rigen97 it all depends on the beam to begin with, i seen vids of ppl using a tea laser beam to pump a dye solution and get it to emit a different color beam out ,of course this means the dye is lasing (ie stimulated emission) ,and fyi all laser materials emit light in different directions before some of this light is bouncing back n forth between mirrors and stimulating more photons in the same direction so that has no bearing ,also some of these lasers emitted by pumped dyes in a cell do not even have mirrors but the beam is still generated because it has such high gain
Retired Astrophysics Professor: This absolutely incredible series brings dry and dusty physics to amazing life!!
Well done!!! Unquestionably it inspires everybody to want to know so much more!!
This is teaching at its very best!!
Dan, thank you very much for stopping by. I’m honored you find my content refreshing and educational. Truly. Physics, to me, is extremely tangible and applicable - and I aim to prove just that.
"TEA Laser" *sips tea*
Ah! you're the first to notice.
came here to say this, nice detail
So many teas throughout the video :D
I am so happy you did a collaboration with Styropyro, He's definitely one of my favorite CZcamsrs. This was a great video and I'm glad it worked out for you. I'll mess around with lasers after a ton of research and when my kids aren't little anymore lol. Thank you Jay and Drake : )
I didn't realise lasers could be this mechanically simple!
many years ago, scientific american had one article on N2 laser under amateur scientist (I do not have the exact reference and it is not on the web)
I've heard of plans that are little more than the excited emitter, a polished surface in the rear, a tube, and a hole for the photons to escape on the opposite end. The idea behind it was that only those photons that were on the proper plane could escape while being coherent. It sounds like one could do this with something like a flashlight where the apparatus discriminated all of the unusable photons, but I guess there's something with all of the different frequencies and ranges of them along the spectrum that interferes and causes it to not work that way.
I'm not a ohysicist so I can't say anything for sure in this regard, but it sounds pretty.
Nice! 25 years of IT engineering and my journey has brought me around to hardware. Which, of course, has me going after knowledge in all areas! Focus, robotics... Great Laser! I've added this to my list of projects. Can't wait to build one out! Thanks for your great work!
Amazing video ! You should make a MUSIC TESLA COIL and a FULL BRIDGE RECTIFIER (with electroboom) !
Yeah that would be soooo cool .Pease make a Music Tesla Coil !
Yeah awesome idea for a video !
Great idea ! : )
Pretty impressive. I've messed about with these a few times, with nothing but frustration, but maybe time to try again. I'd love to see more stuff like this, that uses simple supplies to make exciting things, like the circuit you made with water and cups.
What a project. The simplicity of it is astounding yet it has a very technical and weird explanation. This project got me thinking about ruby lasers and I think it would be cool to see you experiment with making your own synthetic ruby and using it! Again a surprisingly easy setup and it would be a great followup video!
Love this project, it's amazing that such a simple setup can produce an effect not demonstrated until the 1960s. You could build a time machine and go make one probably as far back as the early 1800s! Would like to see more laser projects, lasers are awesome!
Would kill for a scope!!!! Great video! Hope you get more into lasers soon and glad you see you chose the right person to help with lasers. Styro was one of the legends on the LPF forums that got me into lasers and the principles behind them. Good stuff, subbed!
Welcome to my channel brother!
On second thought, can you please send me an email, at your first convenience? You may find my email in the "about" tab on my channel page.
I’ve been looking forward to this one, love lasers myself, they are fascinating. Glad to see you got some advice from Drake, his channel is a mine of information. Your beam looked brilliant in the fluorescent ink; brilliant effect. As yes, I’m glad you emphasised the protective eyewear, it’s so important to match your protection to the wavelength you are using. USE A DECENT PAIR! Some people get it so wrong. Thanks Jay for producing another great experiment, nice to watch. I really appreciate the time and effort you put in to making these videos. 👍 from Wales 🏴. Oh yea, I don’t need an oscilloscope, please give it to someone that really needs one. 💫
I have worked with several laser technologies over the years, but this is the first that i have learned of the tea laser, and i am amazed at its simplicity and effectiveness. There is so much i this world to learn! Thanks for enlightening me.
This project is awesome and answers a lot of questions about the unreliability of the TEA laser I built back in high school! Great work!!
I'm always happy to see your mistakes in the videos. It makes it easier to learn from someone else's mistakes as well as how they fixed them. I'd love to see more laser content in the future
This is awesome, I had no clue about nitrogen emitting a uV photon when exited, once again I learned something new from you, thank you.
Nitrogen laser go BRRR.
I appreciate how open you are with the problems you faced making the laser work. I’d like to see 3D printed parts that package up the design into a bench laser.
Made one of these in grad school to do Raman spectroscopy. As a hint: these are super radiant lasers. It helps to put the spark gap at the far outer corner of the top plate. That way it generates a wave across the plate and the discharge starts at one end of the gap and travels down the channel at the speed of light, exciting the nitrogen as it goes. When we tested it this gave the best beam intensity.
Keep up the great content. I always enjoy your work (and keeping my one hand in my pocket has saved my life multiple times!)...
I wonder if this phenomena is related to the "sprites" sometimes seen above lightning?
Possible, I think there is more to a sprite than just UV laser light but there’s something related going on there for sure.
I'm an EE student and am fascinated with lasers. I would love to research those rust removing lasers when I am out of college and try to make them cheaper and more available to regular consumers. I was glad to run into your channel and see yours and others' passion. One thing I would like to see from your channel is to take one of your projects, such as the Kirlian photography or this laser and make a clock with the hour and minute hands being the beam / arc. Or just any sort of homemade conversation piece.
Very cool creation. A great example of how "simple" doesn't always mean easy. What it made me curious about (as a radio amateur) was what kind of RFI that sort of pulsing and arcing generates.
Great video. I remember watching my dad build build one of them in the early 60's. I had forgotten it until now. Thanks a lot.
Awesome video! Although I wont be building one of these any time soon, I still find it facinating that you can make a laser with just random stuff from the hardware store. One project ive always wanted to see a diy crt, maby even with an electromagnet to demonstrate the fact that you can bend the beam with magnetic fields. It is a device that nearly everyone has seen atleast once, but most never give it much thought. It would be cool to see the the technology that was once in nearly every home, and would be a good way to learn about them, and you could even (carefully!) break open an old tv and show the similarities and differences between your tube and the commercial ones.
Great job abd keep up the good work!
I’m extremely upset that this amazing channel does not have at least a million subscribers. keep going jay.
Very cool. As an apprentice electrician, I dont quite get the "FIX" that I crave without fun experiments like this. Also having a Styropyro collab...! You both are genius! Thank you for putting this info out in a safe, structured, fun, and exciting ways for all of us to view!
Amazing video, currently taking electricity and magnetism in college right now and it's amazing that I understand the circuits, capacitors and everything about the voltage and current. Was thinking about building my own but now sure where to get a power supply
It's funny that this was the original idea for my ongoing collab with LabCoatz!
After neither of us got it working We changed the collab project to a Plasma Vortex Cannon
Wow, your videos never cease to amaze me!
That’s pretty sweet! I’ll have to build a TEA laser sometime myself! My kid would love the project (with proper safety gear of course!)
It’s nice to watch my two favourite CZcams celebs collaborate!!
Best collab ever! Seriously though I've been following your channel since you had 10k subs. You helped me to get through quarantine and you made me go to engineering school, so thank you for that :)
I don't even care if I don't get the scope I'm already grateful for a lot of entertaining and educational content
Love your work keep up!
Great collaboration with Styro. I would love to see more.
I am still waiting for the 3D cloud chamber. That would be cool.
All Cloud Chambers are 3D. The device used to detect radiation was 2D but Cloud Chambers are 3D
I remember seeing Justin from The Thought Emporium building one of these too. They look amazing frustrating because on one level they're so simple, there's so little to them! But on another level I can imagine you taking days and days and days gently adjusting gaps to try and get the ------g thing to lase! We all learn that LASER means "Light Amplified by the Stimulation of Electrical Radiation" at school... but styropyro's explanation here really help finally get me to see what that REALLY MEANS!
Just what i needed, ANOTHER project to try! I'd never heard of TEA lasers, down the rabbit hole to learn more.. thanks Jay!
You know they actually put UV fluorescent particles in some clothes detergents (for white clothes at least). That way they can actually genuinely be "whiter than white' as some ads used to say when i was little. You get the white light from all the colors but you get extra brightness on top from the UV getting turned visible.
Not only the detergent, processing of the textile fibres requires many chemicals that are very fluorescent. Thats why most cloths glows in UV or Blue laser. You can scan your living room floor with a 405 nm Laser pointer and see the floor is full of tiny bright stars. Thats the small fibres ripped off your cloths.
Cool laser. I built my first hene and power supply kit when I was 8, since then I have many types of lasers but I have never tried to make a tea laser I may have to give it a try. Can you do something with electrostatic propulsion? Maybe a small light weight plane. I would love a new scope mine was found in a dumpster after flooding and had extensive water damage I purchased. A schematic and replaced the transformer and some transistors but its 30+ years old and always has a new issue and is in need of repair.
I've been watching you for about a year now. I always learn and get new inspirations from your videos! Thanks!
Yet more science I had no idea existed. Quite frankly, I couldn't begin to suggest what to make a video about next, because more than half the time, I've never heard of the things you come up with! Its great to get a glimpse outside my 'embedded electronics to make things move' world sometimes. I could definitely make good use of a real scope that isn't something cobbled together with an arduino and a resistor ladder too!
would love to see styropyro make one of these strong enough to cook a steak
What scares me is I feel like he could pull it off, worse, he might already be doing it
...and seven dislikes from people who never stand up from their sofas...
Cool project, nice to see it. 👌
I really liked the simplicity of the material and that it's awesome for a school project. I'll show it to a professor of my university. Nice video.
Learning much from your channel and been thankfull to you and my father who introduced me to your channel, because he also likes to build a lot of stuff and I need videos like yours to understand im my own pace whats happening. You two definitly sparked a passion for a science field I never knew could be this intriguing. And of course thanks for showing me what a TEA Laser is and the neat little trick with the water!
This project Awesome like a tesla coil, please make a mini drone in which power source is on it like a ufo using the power of ionic wind !
Very cool video, never heard of the TEA laser
Now get ready for COFFE laser
Hello teacher, I am a student of yours. I have learnt a lot of things from you.
*Stay safe, stay at home*
*Love you from India*
Wait until you hear about the tea taser
Never heard of tea 🍵 laser,but they are cool.
I would like a video where you combine hundreds of chips and connecting it to a computer and test its power🤖
I love lasers and trying to get back into it, I was a PMEL Tech in the US Navy and after my back injury has now put me on disability I would like to get some test equipment but the fixed income gets eaten up by a roof over my head and food. Keep up the great work
I never thought a laser could be so easy to build. I will have to look into it. Thank you for showing this project..
That's really amazing! Still trying to wrap my head around how the heck this thing works - need to rewatch the video a few more times. As for future projects, how about using one of those flyback transformers used instead of iron core transformers in some recent microwaves?
Like stated at around 5:30 in the video, the lasing occurs as a chain reaction, avalanche, whatever appeals to your understanding. When an energized nitrogen molecule drops in energy state along the length of the rails, a photon is ejected, this one photon cascades through other energized nitrogen molecules along the path of the rails exciting more photon discharges, because the rails are straight you end up with a coherent group of photons traveling along the same vector as they leave the rails. There is a beam emitted from either end of this apparatus. I believe that's an accurate description, hopefully someone will chime in if I am giving you bad information.
@@blackbeardthepirate7467 yes u r theory was crct.. that is why LASER stands for light amplification by STIMULATED emission reaction
@@blackbeardthepirate7467 interesting, that makes sense. Thanks for the clarification!
@@nigel-matthews glad to help you gain any understanding, it really is a fascinating phenomenon that physics allows us to force a laser into existence like this. Makes you wonder what other kind of phenomena can be "brute forced" with less equipment than one might think possible.
LASER EVERYTHING!!! Totally want one of those new oscilloscopes for my magic school bus!
Hi Cara, can you please clarify what you mean by magic school bus? Please feel free to respond to my email, listed in the "about" section of my channel page.
@@PlasmaChannel Sent!
I’ve just discovered your channel recently. I love your content. I loved the video you did using a drone to capture electricity from the ionosphere, and all the other crazy plasma projects. I’ve learned a lot already, thank you for
Making these.
This is really awesome. I love building "simple" devices like this. E.g. the coherer receiver. Also very finicky, but even cooler when it works.
I've never heard of a TEA laser. Another cool "DIY" project I'm never going to kill myself making.
If you could replicate Rutherford's gold leaf experiment it could be awesome! Such a ground breaking experiment in its time!
Project was great, more collabs with people like styro would be awesome and some projects that are really simple like this (simple as in quick with simple materials) would be fun to see more in the future!
I loved the straightforward explanation of how the process works. Thanks!
One hand rule... As my high school electronics teacher used to tell us all the time "One hand in pocky, no get shocky"
@Reno Simpson Yes.
@Reno Simpson No, Pittsburg.
It would be very interesting to see, whether you would be able to trigger sparks in an electric field by firing that laser trough it.
Sounds like a lader induced plasma channel.
been done with very similar TEA lasers... but using CO2 rather than air as the lasing medium. very high peak power.
As a kid I was always so facinated with how ele trinity work and still am today. I found this really cool that its possible to make a laser with just some stuff at home!
That’s pretty cool! I’ll have to build a TEA laser sometime myself! My kid would love the project (with proper safety gear of course!)
Look who i found. :)
Wow, I didn't know those kind of lasers existed, they look amazing o:, I see that they need a lot of precision to make but, do you think you could make a portable version? I would love to see that :D, also, since this works with nitrogen in air, could it be possible to make a sensor to atmospheric nitrogen level with this?
the atmospheric nitrogen isn't any concern at all. it's nearly constant throughout the atmosphere.
What if you put whole set up in a nitogen filled enviroment will the laser be more powerful as more nitogen=more photons?
Also can the tesla candle be converted into a muscial one for you know date night😂?
The atmosphere on earth is already 78% nitrogen, I don't think the laser intensity would be significantly greater, but probably enough to measure a difference.
I would be curious to see the effect generated by running this apparatus in a chamber filled with noble gasses, I would expect the laser to be the same colors that you expect out of those same elements in neon signs.
@@blackbeardthepirate7467 that would be really fun trying noble gases and also allen keys could be replaced with graphite pencil leads now that i think of it. Also he may be able to make the setup compact by using capacitor instead of aluminium and plastic sheeta to fit into a resonable sized noble gas filled chambers
yes if you add N to the cavity it will be more powerful ,many ppl have built them using N gas pumped into the cavity and it creates stronger lasing that you can see a blue line appear brighter in the discharge cavity and then you can make visible beams using dyes, google lee lab he shows one he made doing that, but there are others showing it on yt vids
@@blackbeardthepirate7467 78% mixed with oxygen etc is not as efficient as 100%
@@ARCSTREAMS interesting, more logarithmic than linear efficiency? What kind of chamber are we talking here, higher than one atm worth of 100% N2?
I built a low pressure version of this type of laser in 1977. It's called a super-radiant laser. Same basic type of power supply, except that I had a 15kv neon sign transformer that was bigger than a loaf of bread and fed that into a full wave bridge rectifier to power things. That was the year that I learned to really fear/respect High Voltage. I also used 10mil mylar, and even then I had to constantly "repair" shorts in the capacitor.
This reminds me of a similar build following an Amateur Scientist article by C.L. Stong in the 1974 edition of Scientific American, pp. 122-128. It utilized a 3 plate capacitor made by etching a double sided PCB, two strips of copper foil, and a plexiglass enclosure to contain flowing N2 gas. What attracted me to the build, was the simplicity of the design, and lack of mirrors at the cavity ends, required in other popular gas lasers of this era, ie. HeNe and CO2.
Congratulations on your build! I've been enjoying your videos exploring the world of High Voltage generators, along with the detailed build instructions to replicate your projects, that are both functional, and nice to look at when not energized.
Some future projects to consider could be...
- Electronic electroscope, using a center zero uA meter to show positive or negative charge.
- Kelvin electrostatic generator, using a battery powered water pump.
- Radial or Cylindrical Dirod electrostatic generator (see Electrostatics by A.D. Moore).
- Bonetti or Voss sectorless Wimshurst machine, powered by small DC motor.
- Safe (non-mains connected), ZVS powered SSTC with 556 IC interrupter circuit (pulse, frequency).
Laser effect is achievable also with sound. Modulating sound on high frequency wave you can transmit sound in straight lines. I have build one and it is pretty cool, but it has some flaws, an osciloscope would definitely help. (parametric speaker)
I am attending electrotechnical college, for one year I haven't touched osciloscope. Everything we learn is only through online classes. I am sick of theoretical studying. If this all continues what engineer am I gonna be? My patreon name is Jurco.
Hey Hey Hey
What buat a musical tesla coil ?
No, only me? Ok
Awesome video showing us alternatives which aren't necessary mainstream. Many thanks for all your time, effort and hard work, it is much appreciated.
Awesome job! That's why I love the Plasma Channel; I always learn something new. Had no idea what a TEA laser was until this video.
I think your next project should be a plasma speaker. Your builds always come out so good, I can only imagine how awesome a Jay-built plasma speaker would be.
I tried it myself when I was 13 and failed miserably
I remember building a TEA N2 laser during my PhD days.. It was fun then, its still great fun watching u do that at a much smaller scale.. Wish we had your channel in 1987! :-)
I love that you collabed with styropyro. I've watched his channel a LOT and love his projects....and yours. I've been interested in lasers and high voltage since I was a kid (about 30 years now).
Honestly this was incredible and also gave me a better understanding and appreciation for how lasers work. I may have to make one with my nephews now!
I'll put this as a challenge out there for anyone who wants to try.
About 15-20 years ago I managed to build a TEA laser using only materials from my parents kitchen... It only lasted a few seconds before there was arching through the insulator... But did work...
Note, HV sources I had were an old CRT TV and microwave oven. I used the TV...
Cool project! Made a GaAs pulsed laser in high school in the mid '70s. Had to use an IR fluorescing target to see it. Fun stuff!
That project is indeed interesting and unique how a nitrogen laser is formed using just arcs and provision alignment
So surreal, how seemingly simple the setup is. Would love to see a more advanced version of a TEA laser
Wow, this is one of those things that remind me that there are still, so many more things out there to learn. Glad to see the colab with styropyro.
I've always wanted to build a TEA laser and now I have a great step by step tutorial. Thanks. I would also love to see a tesla coil made out of a taser. I love my bug zapper racket and arc lighter tesla coil so much! Thanks for the great content!
Wow what a collaboration! It's so fitting. styropyro is just so damn knowledgable, he really is passionate about this stuff.
I'm always in awe of the things you do! Most of the time it's above my head, but I'm slowly learning with the hope I'll be able to use the stuff you teach us for one of my projects. As for project ideas for you, honestly, I can't think of anything that would give you more joy than the stuff you come up with already. So keep on having fun and thanks so much for letting us come along for the ride.
Ken, thanks so much. What you said honestly means a lot. Glad you're here to enjoy the ride with me.
This was pretty cool. I honestly have no idea what project should be next and I don't even know what I would di with the oscilloscope because I have no formal training in electronics. I'm still learning and really enjoy your videos
These lasers without any kind of collimating optics or mirrors always blew my mind... It would be cool to see more laser stuff on your channel! High voltag related of c ourse
I read about these when I was 13 and wanted to build one. Everyone talked me out of it then haha, not anymore. This hit the nostalgia button. :D Would love to see some audio modulated plasma/Plasma speaker uploads :O
Amazing that this laser works. Usually you need 2 mirrors to resonate the beam and strengthen it.
I love this video dude. It is so cool.
The things you do are already very great, so just keep doing it, we will watch with pleasure!
the things that you are made are extremely clean and beautiful ............and very well explained
thank you plasma channel
I had heard of TEA lasers but I always thought they involved the drink! Nicely done, glad to have learned what it actually stands for!
Never heard of TEA laser before but now I'm going to build one. I'm very comfortable working with very high voltages so this promises to be a fun project.
I had no idea this was even possible! was cool to see a mix of physics, chemistry and electrical elements that all made this possible. Something id love to see on your channel is a Jacobs ladder. I've always been mesmerised by them and think it would be cool to see how you would make one.
I really like messing with UV and fluoroscent dyes. As next project I propose small VTCC(for example on GU-50) or film explaining QWCDRSSTC working mechanic.
Love to see this lase through some optics for a better beam profile. Looks so fun, who could resist making one? I know I’m gonna try! Thanks.
I enjoy your videos and forward them on the my granddaughters so I can get them interested in science. I’m glad you do projects that can be done at home and am looking forward to building a cold plasma torch! Awesome job and thank you for making them
I love how simple this laser design is.
It would be really cool to see how plasma acts in an induction heater.
Yet another mind-expanding video from you Jay! I really had no idea about that way to generate a Laser. *Thank you* . Reading between the lines, i can only imagine how frustrating the process was, and sharing it with the community ups the game for everyone. Kudos. BTW. I would *really* be able to use decent scope. the crappy USB scope I have is seriously limited, and I can't afford better :|
Definitely enjoyed this one. Sometimes the most simple things become the most complex. I've always enjoyed how your projects are very clean and well put together. They're items that I can build and look very professional. I built one of your mini Tesla coils using the plasma lighters and use it for demonstrations at my makerspace. It has even been on the local news. I've always wanted a clean looking mini Jacob's ladder. Maybe for one of your future videos? I know they're pretty simple at their core, but I know you'll make it classy.
I can't believe how easy this lazer was to make. Love the channel!
i dont understand anything about electricity and i wish i did but this guys videos are beyond fascinating.. it makes me want to learn more! thanks for the awesome content!
That was pretty sweet! I have never seen a TEA laser. Now I want to make one! You should see what it takes to increase the power output. Maybe longer rods or adjustments to the capacitor plates or resistor or maybe just more power via a larger spark gap. You could measure the power output with a UV light sensor.
This project: these things seem really finicky. Glad you took the time!
Future video: A more reliable/more powerful power supply than the one noted previously.
Thank you!
This was 🔥, I hope to see more laser energy content on your channel. Appreciate the effort you put in making these videos !
Thank you Abel
