Thank you for the information. Very helpful
But I have a question for you
I need a laser that can project through 2x2 inches designed object and withing 3 feet or so It will project the design to be about 2x2 ft in day light ?
Is this possible.
I appreciate the help in advance thanks
3 question I got 650 nm.red laser 1 how dangerous is this laser ? 2 what's the visibility like ? 3 what kind of batteries do I need to purchase ?
Excellent video! Love learning about the physics behind lasers!
Matthew Wise Me too! Thanks a lot😀
I have to show this video to my science teacher. I'm going to tell her, that we don't care about photons, quanta and shit... just BRING ON THE SQUIGGLY LINES!
Who needs the technical terms!
cyancoyote lol
XM360 true tho
Physics teacher:nooooo, you must describe light with photons
Me: haha squiglly line go brrrrrrr
I just ordered a 860mw 638nm red/orange laser im very excieted to get it!
another great video! you explained it very well
keep up the good work bro I love all your vids your voice makes it even better, nice work 👌
Thanks a lot!
too nice explanation and reviews......too impressed......please continue to make reviews of the laser pointers please..........too nice work...........
...
The laser you had in the very beginning, could you do a review on the green version of that
Already knew all of this but your explanation is really good, kept my attention(Like all of your vids)...Keep it up!
Thanks a lot!
Mos Def
Thanks man, I really appreciate the informative video!
Bibek cherry
Simply thank you.
Very interested awesome video love lasers
Great job
Cool thx man keepem coming.
Love your videos. Have you ever tried pointing a laser to a crystal ball (quartz)?
Thanks a lot.but i have a doubt, a light wich deviates least in prism has smaller wavelength or larger wavelength?
You explained it really well. Thankyou
uphojhjjt
greatest video
the red light is in the region of 700 nm so it is so far from 555 nm, so What is the wave length of the red laser? thanks
a simple question if the squiggly line is more strechen out will the laser go further?
i just wanted to know:does the lasers hurts you? is it harmful or not?
very nice
Which laser is the best for detecting small particles ? in an experiment
Thanks helpd aloth
!cool new intro
would you please explain mw alson in lazer lights i will be son thankfull to you
Thank you
I got a gatling laser from jetlaser it's a green 500mw 532nm laser, is that any good?
hey dude! lovin your videos so far on the lazers. just wondering, i got a 1MW lazer a few days ago and it hasnt come yet, its green so will the beam be visible?
@Ronnynerdy1watt will blind you
200mw can blind you
The best
thanks
Good video. Could you explain mW and wattage, also some lasers are rated in miles, whatever that means. And why are focal length and focus important, or are they? Thanks
for the miles thing, its supposed to be how long you can see the laser from, but its p much fucking useless, ignore those
Watt is a unit of energy and mW is 1/1000th a Watt. It is denoting power output typically of the beam itself and not it electrical requirements to power. Lasers rated in miles is a marketing term and not a standard you should ignore it for other ratings. To cut or burn with a beam you need to focus the beam to a single small point and concentrate the power output of the laser into a smaller surface area and all of this including collimation and divergence ratings are more about the optics then the laser itself. Divergence ratings at distance indicate how imperfectly collimated the beam is or how straight the light is traveling for the whole beam and how much spread or larger the dot will be at a specified distance. The atmosphere will scatter light traveling through it anyway here as that is why the full spectrum output of the sun looks blue when it is really blindingly white.
I once shined a red laser on a white door. It made those squiggly lines
:3
Link for that green laser ?
Sorry man i think your graph in 3:12 is not really exact because we see som ultraviolet light a liiiiiiiiiiittle bit
Hello , so can you give me a shortened paragraph about the ‘laser wavelength’ ?
What about if you want to know the distance
Hey my laser light doesn’t have beam, the lightwave are not visible, but I can see the light hitting the object,
My something wrong with my laser or batter ?
and do the watt matter?
How much mW is that red laser and where you bought it from? 0:44
So what would cause a green laser to change color on contacting a surface? I have this orange felt if you shine the laser on it it turns the laser light white on contact, And the light reflected from the laser off the felt is white. Why dose this happen, I genuinely don't know? The laser dot stays the same color on every other material regardless of color, or texture. But as soon as it touches the orange felt it turns the light white on contact even cause the glare reflected off to turn white.
what kind of fogmachine do u use?
A vape
I have a question
Why we measure the wavelength of He-Ne laser and we already know it
thx =D
thx
Can you make a vid on how long they go up to and which are best
Kyren Me green, 532 (usually) is the most visible
Nice work I like all your vids Please reply it will make my day
Thanks a lot!
OMG you just made my day you actually replied to me
Which color should I choose to use as a beacon at night?
The one with the most visible beam from miles away.
Green is best....
Is there an invisable burning lasar?
What would be the best one?
That would be a infrared laser but it will give you cancer
whats the best cheap laser with visible beam that is also safe to use for beginners

Can I get any hand held digital instrument to measure the wavelength of a visible colors 400_700 nm.if yes pls share the address and price
What determines the wavelength of a laser ? Is it the power source or the gain medium?
i see something on video like that ..the wave if i Remember was created inside the diod,and was made by the distance,inside we have a perfect mirror and some half mirror,for me the distance betweeen this two create different wawe. i can't immagine more options Sorry
I'm Just a random guy affascinated by laser and electricity
Dear can you explain why 532nm have frosting effect and 1064nm does not have while using in q-switch nd-yag?
The 1064 is known as the gentle giant, it penetrates deeper in the skin whereas the 532 hits the epidermis causing the frosting
what do you need to study if you want to make lasers and stuff like this guy
How far
So purple is the strongest cause it has shorter wave length and carries more energy than any other colour
Yes
so are the 532nm also the most powerful or just the most visible?
They are one of the most visible colors. The closer you get to 555nm, the more visible the laser will be!
For burning stuff blue is the best and Ir
@@XM360 Are there any sellers who have 555nm diode?
What wavelenghts can damage the eye more?
Windows all of them but some give off UV light which can harm your eyes without you even knowing
The ones with wavelenght lower than 405 nm?
lol i learn this in my science class
What color does 637nm appere
Red
Which eBay seller am I better off buying the blue laser from??? mylike168 or gome668...Might even be the same EBayer judging by their names and location??
mylike168 or gome668???
Rizzi Chhipa thanks for the response and the input.
Which laser light strongest
GeTR3kT depends on your wattage. If they are all the same wattage the lower the number is the stronger it is
Does 758nm light look green
no that would be Infrared and invisible to the human eye
Who came up with the measurements? Why is green and orange the larger ones in your presentation? When I google search this, it seems like the measurements are all different and the colors are in different sizes. Why is this?
I have seen yellow lasers but they are too expensive unless you have tons of money and collect this sort of stuff.
Ya hopefully prices come down as the technology becomes easier to produce
We do have many things we would not be able to afford at all if that didn't happen. Part of it also happens as more people buy it and that helps offset the costs and make it nice and affordable when it should have cost a fortune to buy and even once did. 3D printers are a good example. There are some that cost as much as a good car and now there are *some* that can be bought for just a couple hundred dollars.
XM360 I'm thinking about the SPYDER III S3 ARCTIC, has the price gone down from $250? and I do think that WICKED LASERS does ship to the US now but it takes a few months.also could you please send me a price total for the ARCTIC, KRYPTON,and maybe a few other lasers that have the most visible beams for UV and red lightweight handheld laser pointers.really appreciate it.😀😉

or the 520 NM, that seafoam green color.
So the color of,laser has nothing to do with the power of the laser? ....it seems years ago imremember most of the cheap lasers were red and the stronger ones seemed to be green....
Things were only that way because the commercially available reds were weak, and then people figured out a way to cheaply manufacture powerful DPSS greens that were much stronger. But you can have lasers of any color and power (based on the available technology)
But sir wavelength is just a colour ? When we talk simply
Buzz light year night light in the corner
The laser is dangeours
Green:500mw
Red:200mw
Blue:1w
Purple:100mw
Which one has the potential to be the hottest
not too helpful. I wanted to know difference between ordinary light wavelength and laser wavelength.
first lol
Which one goes the farthest
Green goes the farthest but blue burns the strongest.
