Here a BEAST blue laser in the class IV range burns some stuff. This laser is extremely dangerous!
Wicked Lasers Arctic Spyder III laser wanters: If you even think about buying one of these, you must be extremely careful and take all safety precautions when using that laser! 1W in a handheld laser is very dangerous.
More videos of this laser coming soon, just waiting on a new lens for this laser. Current is now at 1.25A so it should be outputting 1300mW or so now.
I built this laser from a lot of spare parts and the Casio laser diode.
