400 mw Handheld Green Laser

A short video demonstrating this newly built laser. Various things get burnt. The laser is assembled in a custom machined aluminum host. The green module is a 400mW from o-like that peaks at over 600mW and settles back to the mid 400's as it warms up. The battery is a single 18650 lithium ion cell.

I hope that you enjoyed this video, please like, comment, and subscribe to my channel for more laser and other tech related action!

Since when did o like have 400mw green laser module

@laserloverkid O-like occasionally get in a line of large green DIY modules. These are about 1" diameter, and have an adjustable lens and preinstalled driver. When they are in stock, they are available in powers up to 600mW and do deliver their rated power. I got mine several years ago, check the o-like website every few months (they have none now) or email Susie at o-like and ask her if they are getting these again soon, or if she can order one for you. They run off a single 18650 li-ion cell.

@birramorettisuper

Don't see why ... Just burning steel wool here ...

[doubleshotespresso]

[billg519]

@doubleshotespresso

Fine steel wool.

[laserloverkid]

How much will it be

[ahammer180]

@billg519 Metals reflect light very well and in this case in an uncontrolled manner.

Inevitably, a few rays, albeit attenuated, hit your eyes. Here we only 400mw, but if we had a good power this game could be dangerous

how do some of the laser pointers have beams.....and others don't?

@Sgtrambom60

Lighter fluid is clear and will not be heated/ignited by the beam.
