Have you ever played with a laser pointer? How about a laser bazooka?
Laser pointers usually cap out at around 0.005 watts.
This guy built a “laser bazooka” that, at 200 watts, comes in at about 40,000 times stronger than that.
While YouTuber styropyro built his bazooka out of materials torn from a bunch of broken DLP projectors and “a stack of lithium batteries,” this… isn’t something you should build at home. It’s fully capable of starting fires if you point it at the wrong thing, and would permanently wreck unprotected eyes (note his MASSIVE WELDING MASK) in no time flat.
Says Styro, “… it feels like I’m holding a bolt of lightning in my hand.”
