YouTube user styropyro, a.k.a "The DIY Laser Guy," created 3 watt lightsaber two years ago, but he has grown up and left childish things for children... and created a totally grown up 40 watt laser gun!
"The output of this laser is complete insanity, and is made up of 8 parallel 5W laser beams totaling to 40W," styropyro wrote on YouTube. "The parallel beams are manipulated with lenses, sort of like how a choke modifies the spread of a shotgun blast.
"The massive diode array is powered by a huge lithium polymer battery pack (capable up dumping 250A) and the laser array is regulated by a whopping 24 LM317 drivers."
"Dangerous is an understatement for this thing," styropyro said in his video while shining the laserbeam around the room. "There is no, no good reason for anybody to own anything this powerful, but because it wasn't illegal for me to build, I decided to build it anyway."
The young scientist wrote that he hopes to build something bigger and badder sometime soon.
