Green Lasers: What Can Certain mW Do?
Vložit
- čas přidán 2. 06. 2010
- This video compares some of the most common power outputs of green lasers you can buy these days. I compare the difference in visibility and burning between 5mW, 15mW, 35mW, 50mW, 100mW, and 150mW.
Important info after watching this video:
-I used fog to bring out the beams.
-This video is only about green lasers because they are nearly always fixed focus and have a small beam diameter.
-I mention powers where tricks are EASY to do. You may be able to pull off burning tricks with less power than what I state, but these are bench mark powers where you can reliably do these burning tricks.
-Additional focusing with extra lenses can lower the threshold of what you need to burn. Watch my focus video for a better explanation of this.
-I go by actual power of these lasers in this video, not advertised. Nearly all cheap laser sites sell lasers marked from 100mW to 300mW when in reality the actual power is much lower.

Straight to the point, well put together and easy to understand. Great job!
I seen what you did there 😆
you need eye protection for anything over 5mW, 35mW will still burn holes in your retina.
Big fan nro
Anything greater than 1mw sweems the current recommendation as of 2024. Since there seems no accurate way to tell the power of a laser for the average end-user, just do not look at a laser. It is very apparent why powerful lasers pens are no longer easily purchased.
I just ordered a 200mw laser.
Where from?
mine is 50mW…

This is so awesome. A lot of knowledge about something I don't use in a daily basis, but still so awesome to watch.
Very nice video! simple but im so glad someone took the time to demonstrate these all. I was looking into getting for for a weapon sight and i wasnt sure how much mW was enough. Thank YOU!
so 15 mW was good for you?
@@upseguest 15 was good for me. For green that is. I wanted to be able to see the green dot in the day at a reasonable distance and it did just that.
Hey man! I really love your videos =) They are really good if i want to know anything about lasers or if i just want watch you burn something, like with your homemade ones. Keep up the good work!
this video was the video that introduced me to high powered lasers. NICE JOB STYRO!!!!!! :)
I recently bought a 5mw green laser pointer and it outputted 35mw. I'm happy with it C:
It also looks exactly like your 35mw laser.
Amazon?
@@Exaspatial if you want a 30-80mw green laser just buy a laser 303 off of eBay
Nice user name

These are all diode pumped solid state (DPSS) lasers... Old school. Lets see the 520nm direct green diode lasers...I hear Nichia's got a 9 mm, 6 watt 520nm diode coming down the pipe. The 6 watt 445nm blue's are already on the market frying eyeball's...Imagine 6000mW of green beam lasing the sky..."I become death...The destroyer of worlds"...And retinas!
Oh man I need that 6W Nichia beast, although I bet it will be awful to drive. Green LDs still have terrible efficiency and need to be improved, because 6W of 520nm takes about the same power to run as roughly 30W of 450nm.
A couple of 18650 li-on cells...2700 to 3000 mAh should store of enough juice to run for a while...The right driver and a copper heat sink should provide a decent 30 to 60 second duty cycle...It'd be a good burner. I have a 9 mm green in a mini MXDL host...peaking at 1.25 W with a linear driver...Power supply is one 14500 - 3.7V 2000mAh li-on cell, with a small aluminum heat sink...duty cycle is 20 to 30 seconds on/off...It's a stealthy pocket dazzler.
You'd need to have some serious heatsinking on that one. Sanwu could probably do it commercially at a reasonable price.
Check out Rick Trent's videos on You Tube...He's already done it in a handheld host with a copper heat sink and 1 minute duty cycles. 6 watt Nichias in the 440 to 445nm wavelength...He is genius.
I think you can increase the output by heating the connections inside the laser, but as I'm sure you've been warned, the diodes in weaker lasers are usually tempermental and can become unstable should you try and modify them. Hope this helps.
I brought a '1mW' laser pen that pokes holes in bin bags. Yep, cheap eBay lasers.
Same dude!
Tell me the link to the laser pls cus I need to buy one like that
Just look for links claming 'powerful'. They're always overpowered. I estimate my 1mw (labbled 5 mw :p) is approx 35mw.
I konw but it a: wasn't listed as 'powerful; and b: was listed as 1 mW.
Hi could you please share the link with which you bought it? Will really appreciate it thanks
At 1w everyone within a mile says "HOLY SHIT"
@souljasai yeah its over 2 years old, its a great laser. i would love to have it metered to see if it is still putting out near 180mW like it used to, green lasers do degrade over time because of the complicated workings of it.
Will yellow lasers also degrade over time, with much usage, as well?
Big fan bro
Just bought a 50 mw green laser. I cant wait for it to show up! Got it super cheap!
Is it good
yep, thanks to you ive ordered my 1000mw green laser a few minutes ago
I've had low level lasers to my eyes a couple of times when I was younger, and I can see perfectly fine.
Shouldnt play with them like dat doe
Low level like a 1mw red for cat pointing maybe-
I have a green laser pointer ,it says on the pointer output power 200mw but it can't pop balloons or light matches wave length 532nm
Very informative, thank you for the video.
Thank you. i've ever looked for a video like that.
It depends on how dry and thin the wood is. I have a 1W laser like you and i can light match sticks on fire (the wood part not the red phosphorus part). But I wouldnt expect you to be able to get a big log alight. If you had some dry leaves or pine needles around you could make a fire that way. All it takes is a little smolder.
I can buy a 50000mw from aliexpress good deal?
This dude got scammed 5 years ago

@@user-fh9mf2hk6j dude I was 14 XD I also didn't buy it
@@boaz08 Wow. I really didn't expect you to reply. But yeah, it's all good if you didn't buy that. I hate Chinese websites selling you crap saying that it's extremely powerful while it's not worth more than three bucks.
@@user-fh9mf2hk6j i got a 10mw i higly doubt it tho it is warm when aiming at skin for 10sec
Wow, didn’t realize until now that it was you who got me into my laser pointer phase so long ago lmao
thank you so much i changed my mind on what to get
Thank you very much for this informative video.
wow 8 years
It depends on the power of the laser. From 1-499 mw, its safe to look at reflections without laser shades (however it is still required to wear shades for anything past 5 mw, for, direct exposure could cause some serious eye damage). From 500 mw on, it is NOT safe to even look at reflections the beam makes.
did you use fog to make the beam more visible? And also, where did you get that 150mw green laser pen you showed us in the video?
this video really helped me what lazer with what mw I should buy
I just purchased a rifle-mounted light with an integrated 5mw green laser. Can you really see the beam itself with that thing normally like shown at :24? Or did you throw in a puff of smoke or vapor to make the beam visible? If you can see it, might kind of be a bad thing if you can trace a big green illuminescent line back to the person with the laser.
@Dylan Coakley Oh =(

Great.....
There are a couple of 10 watt (10,000mw) lasers on sale for around $55 on AliExpress right now. They come with glasses, case, 5 star heads, li-ion battery (2 18650 cells) and they are very powerful. You can only use these for a few min then you have to let them rest or they will over heat. They have a 150 watt co2 laser tube on sale too, but you don't need that, you can do some etching on the car down the street with it but that bright line will lead them right to you.
Great video!
Where did you buy your 35mW? Please tell me! Thanks!

@@rodrekak8081 what was it like
@@Slidehhy I bought one, its a scam :/ Real power is 5-15mW, really disappointing, cant burn a match or other things
@@Rektonator mee too! :/ I just got a 500mw laser that cant light a cigarette like it was advertised... I'm trying to see if theres a way to adjust it rn. It however is slightly brighter than my green laser 303. Luckily I didnt pay too much...
if they were red then I would put them in my aperture science Im building in the garden!
TIME FOR TESTING :D
Nice vid! Helped out a lot
Cool I have a 35 mw One Abd i just bought and i Lovvvve It Great Vid Btw
nostalgia. 2008 Those days when Green laser pens were 12 bucks and actually worth more than that. Now they are cheap garbage made of pure shit. Not even worth 5 bucks.
and where did you buy these?

Nothing of course xD
Where can I get a powerful one on amazon?

Can you give the link to the greens 200mw please? Thanks in advance.
very helpful video thanks
Hey for a 230mw do you need eye protection for just fooling around? Of course assuming not point in eye. But just like pointing at wall or lighting match.
Yes, you will need them for sure.
Nah. Just dont shine it in your. My friend has a 1400mW blue laser and we dont use eye protection
If I have a 100 mw green laser pointer, will I need eye protection?
where did you got it?
boostercontrol100 could a 30000mw laser burner cut/burn through 1/4 of steel?
i bought 100mw one :)
Useful info for 2019
Have you ever came across an ancient comment you made and not understand why you wrote it?

Nice experiment 😊🎉❤
I have a 100 mw laser pointer and it can cut into a cd disc ,,, it cost me only 20 euro
Waar heb je hem gekocht??

my 15mw was 20 euro 😑I was ripped off
can you provide a link to the website you got it from?
i bought a 100mW green laser from a nigga in rome(lol),god damit it so fucking powerful XD,in the night from my house i like see the green radius that across my city above(3-4 Km) and it's arrived to the countryside,and over the hills,it's really amazing! 100mW forever!

Cool lasers you got there
I'm assuming 1 mW won't do anything?
Yep
my in the bathroom?
Yes
Well did you RMA it?
Also what did you LPM it with?
TEC heads tend to be quite crude.
Lastly, DPSS lasers tend to have a high volatility, was your DL warmed to 30C when you LPMed it?
+styropyro man can you tell us how to remove the diode from the 35mw laser pointer because I have one and I don't want to break it
MUHAHAHAH my 2000mw is visible even in broad daylight and it's a green too, so easier to see the beams
Make it invisible and burn a child’s clothing, send to my insta. 🙏🙏
@@midobula4797 OMG HAHAHAHA
wtf today i bought a laser (YL- 303) and it says that is has 2000 mW output power
Please don’t buy lasers without prior knowledge, the laser you have is 2W, it can cause permanent blindness the instant you turn it on without laser goggles, always wear the appropriate laser goggles for your laser.
Just what I needed
My favourite mw is 80. It's relatively safe and can burn through bin bags with ease. And it's great for astronomy!
@@Atakula383 Where were you 2 years ago when I was retarded enough to use an 80MW laser without eye protection
@MrMortjon quote from description "-Additional focusing with extra lenses can lower the threshold of what you need to burn. Watch my focus video for a better explanation of this."
in this video i just tried to demonstrate what power you can reliably do these ticks. i've pulled off match lights with 30mW
Big fan bro
That was nicely informative
nice, simple, informative video .. well done :) like
at what point would it start to damage/hurt your skin? like say you were to shine it on your hand..
For a 100mw green laser with Kaleidoscopic attachment does it make it safer or still very dangerous for the eyes?
Where can I buy a 35mw green laser like the one in the video?
can i have a suggestion for a 5mw laser pointer?
Thanks for reply man. What about buying one from Sky-Laser if I didn't want to build my first one
got a 100mw green should be here any day :D can't wait to see how it works.
Results will vary I suppose. I found that 50 mW green (metered at 55 mW) is just barely visible in lit areas, but it can pop a black balloon. It can put a small pinhole through electrical tape in about 1 minute. This is an Optotronics laser with a small diameter beam and extremely low divergence. At 300 mW (metered at 307 mW), a green laser will burn dark paper when unfocused and also light a match. When focused, it can put some shallow holes into wood and burn through a CD case.
how do you get a beam to come out of the laser my laser just shows the dot where ever i point it
*wow...never knew about this...interesting..thanks*
Could you do one for blue lasers? Or is it more or less the same. Looking to get a 1W blue laser
where can I buy a green one like that with a strong beam you can visibly see
That could be that you arent holding the match at the focal point of the beam or that your batteries are bad. In a green laser like that, you usually can't adjust the focus of the laser so you'll have to find where the beam is smallest and use that to burn. Also, if you color the match black with a marker it will help absorb most of the light coming at it and burn faster. White surfaces don't burn very well when it comes to lasers.
Good video.
i'm interestged on the 50 one, where did you got it
man your vids are cool! im subscribing!
If i use 300mw, 808nm ir diode, and use crystal to make it green, how much mw the power will be?
So if I have 100mw laser and I just use it as a pointer then do I still have to wear protective glasses? Because I wouldn't look at it directly just look at the laser beam
One can see the green laser beam at low power more easily than other coloured beams because the human eye is most sensitive to green light. The light that you see from the beam is actually reflecting of dust/air particles. You only see a very small amount of the photons in the beam, as most of them just keep going to the target and never reach your eye.
This is also the source of the "green is brighter than red" myth. Green 5mW is the same brightness as red 5mW. The green just LOOKS brighter because of the eye's colour response.
It's also why NVG system displays are usually green.
would it be worth making a video on what mw RED lasers can do?
0:59 DEATHSTAR LEVEL REACHED
I can't light matches unfocused with my 100mw green laser? And I can't really see the beam in the day, it's very faint. I have a power certificate that says it is 105mw stable, but it was done without the IR filter. Can the filter make a big difference?
I own a 200mW red focusble laser and lights matchs with ease at 26ft. Fun to play with.
Hello there , I would like to ask something , I want to check parallelism of pieces of wood so I need the most thin beam possible and also the most round
in a distance of about 10 to 20 meters could you tell me where to search?
the balloon part was epic
Can you use another laser (like an Arctic S3) to "lase" a ruby rod instead of a flash?
it would be nice for an attachment on a AR upper hand with hand button to turn it off and on at will
I have a 250mw from Laserglow. I can say it is pretty fun to use.
150 mW where did you buy?
Or did you make it?
If I might ask, is your laser the Spyder Krypton laser? Because from my experience, 1000 mW green lasers are pretty hard to come by.
Can you tell me where you bought the 150mW? Thx
What laser did he use with 100mW and 150mW? If available link please.
What strength laser do you need to see the beam without a fog machine?
Please help me, where i can buy a good and not so expensive Laser Pointer ?
any idea how to focus the beam small enough that it cuts faster? is it possible to make say, a 2 watt laser focused enough to be a weapon?
Where do you get these from and where can ibuy lasers using paypal
is the mW output label on the laser pointer accurate?
What kind of battery technology powers the 150mw laser?
I believe its a CR2 or 16340 lithium ion since its a CNI GLP
