@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.
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!
@Jean Marie Bigard. it's not too hard to find a 50 watt CO2 laser, but a 50-watt green? highly unlikely. Except for say an extremely expensive lab laser, that would be out of most consumers budget range.
@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
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.
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.
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.
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!
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.
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.
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.
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.
@@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...
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.
Hey great video. Check out my laser videos on my channel (this is not spam) But if you love lasers you will like my videos. Please subscribe check my page! :)
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.
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!
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.
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.
The Rayleigh scattering effect causes a laser beam to be increasingly visible as its wavelength approaches the size of particles in the air. The smaller it is, the more chance the light will scatter. Laser beams in the 550-410nm range will be much more visible than 650nm red laser beams, given equal output power. A 15mw 532nm laser beam is more visible than a 200mw 650nm laser beam, given the same environment. It also explains why the sky is typically blue. It should be noted that fog was used in this video.
Try searching for: HOW TO TURN A 5MW LASER INTO A 100MW LASER in youtube. It may give you a better idea of what to do. If that doesn't work out, try wickedlasers. They sell some INSANE lasers that are brighter than you could ever need. They aren't cheap,(about $300) but they're worth the money. I think for another $50, you can buy a lens kit you can use to dial down the laser output to a safer level as well as cool effects. you can also use the focusing lens to burn through things.
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.
While i highly doubt that it will be a quality product. I hope the best for you. Oh and quick tip, with green lasers you cant usually adjust the focus. So find the focal point of the beam and use that for burning, it will be the most effective at lighting things on fire.
Just so you know, I have a laser that looks exactly like the "15mw" laser you've shown here and when you place an 1064nm cutoff filter in front of the beam, the laser power drops down to about 3-4mw. Which means most of what your power meter is reading is in the IR range of the spectrum. This is probably the reason why your 5mw looks nearly as bright as your "15mw".
Fat Boi No, I'm assuming that this laser uses neodymium-doped yttrium orthovanadate (Nd:YVO4) crystal which produces 1064 nm wavelength light from the main spectral transition of neodymium ion. But I guess it's possible that it's using a 808 nm wavelength infrared GaAlAs laser diode pumps a neodymium-doped yttrium aluminium garnet (Nd:YAG). Regardless, I've checked with both an IR band-pass AND an IR cut-off filter to verify my hypothesis. When I place the IR band-pass filter in front of the laser, absolutely no green light (nor anything in the entire visible spectrum) passes through. And the IR cut-off filter is nearly colorless and appears to be essentially clear. Regardless of what the exact IR wavelength is leaking through, the proportion of IR to 532 is very high. With fresh batteries I get a reading of about 25mw with no filtering. Filtering out the green I get about 22mw.
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.
You can buy them from various stores. From your high quality CNI , DragonLasers, etc. To your middle of the line, O-like , Techhood, Laserland ,Lazerer. To your overpriced and rubbish . WickedLaser,etc. Personally, I'll recommend you to head towards LaserPointerForums to understand the basic safety and mechanisms of lasers. Perhaps talk with few of the hobbyists there. They surely will help you get on your feet. Treat a laser as you will with any powertools. With great care.
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?
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?
I suggest buying from novalasers or optotronics. They sell very nice laser pens and they are always overspec. Although it's not focusable, it will burn things without aid due to the tiny beam diameter. If you really want to focus it, you can use a magnifying glass. Be sure to buy laser goggles. P.S. Always do research on a company before you buy from them, for lasers at least. 90% of the time, lasers bought from non-reputable sites will be underspec crap.
I bought a 5mw pointer but after 30 seconds of use it gets extremely bright, and I can sort of see the beam in daylight. It's really dodgy, what would it's actual power be?
actually, its a common misconception about higher laser power = higher ability to burn things. its ability to "pop" balloons and "burn holes" also depends on the beam width. if the contact area of the laser pointer and the plastic is smaller, then the energy is more focused, and it can burn stuff easily. so theoretically if u focus the beam enough 10mW laser can also burn stuff.
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.

How come the beam is visible? It should light only some particles in air, not the air itself. We generally don't see travelling light.
The Rayleigh scattering effect causes a laser beam to be increasingly visible as its wavelength approaches the size of particles in the air. The smaller it is, the more chance the light will scatter.
Laser beams in the 550-410nm range will be much more visible than 650nm red laser beams, given equal output power. A 15mw 532nm laser beam is more visible than a 200mw 650nm laser beam, given the same environment. It also explains why the sky is typically blue.

I believe its a CR2 or 16340 lithium ion since its a CNI GLP
0:59 DEATHSTAR LEVEL REACHED
Hi, recently, i bought a 5mw lazer pointer on amazon.com. But on it, it wrote:
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?
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?
That was nicely informative
I suggest buying from novalasers or optotronics. They sell very nice laser pens and they are always overspec. Although it's not focusable, it will burn things without aid due to the tiny beam diameter. If you really want to focus it, you can use a magnifying glass. Be sure to buy laser goggles.
P.S.
Always do research on a company before you buy from them, for lasers at least. 90% of the time, lasers bought from non-reputable sites will be underspec crap.
the balloon part was epic
Can you give the link to the greens 200mw please? Thanks in advance.
Just what I needed
For a 100mw green laser with Kaleidoscopic attachment does it make it safer or still very dangerous for the eyes?
FYI, He is filming in a very foggy room, that is why the laser beams look like lightsabers.
good video ,very useful !
You can't sea the "beam" itself. However, the light from the bem lights up dust in the air and that is what you actualy sea - lighted dust.
I bought a 5mw pointer but after 30 seconds of use it gets extremely bright, and I can sort of see the beam in daylight. It's really dodgy, what would it's actual power be?
its actual power should be, as stated, 5mw. where did u get it?
So are they eye damaging if you look at the beam? (as in you don't point the beam into the eye, just look parallel to it).
Varun Ananth no but it can cause blurred vision if you look from a 45 degree angle front ways.
actually, its a common misconception about higher laser power = higher ability to burn things. its ability to "pop" balloons and "burn holes" also depends on the beam width. if the contact area of the laser pointer and the plastic is smaller, then the energy is more focused, and it can burn stuff easily. so theoretically if u focus the beam enough 10mW laser can also burn stuff.
at what point would it start to damage/hurt your skin? like say you were to shine it on your hand..
