Green Lasers: What Can Certain mW Do?

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.

so lightsabres ARE real

Excellent vid very useful info

where do you get them from!!!

Please can you help me, my laser it says its a 1mw laser but it is soo powerful and looks like your 15mw laser visually and the actual laser(green thing) is the same (as i already said as the 15mw on here) so does it mean there was a fault with the sticker machine or summat?

Some MW's can waste ur cash.... o.0

He may be using fog.

I bought a 1mW green laser from eBay & can't see the beam at night.

Wavelength is 532nm. Class IIIb (3b?)

Is this normal?

you can bye thos'e in thailand:)

@bengangster123 you would burn yourself. i have a 5mw 405nm focused, and it can burn my skin PRETTY fast :) i mean, you wouldn't get skin burns, for you would be able to withdraw when it started to burn, but you will "burn" yourself.

[najsbajsmedmajs]

@iBlob1000 yes.

[bengangster123]

@iBlob1000 no, but you would feel that its a bit warm on ur skin
