A high powered laser a DIY reverse telescope makes a device that burns things much further away than any of my other laser creations! social media sillyness: shorts channel: instagram: patreon: backup channel and b-side videos: discord: In the video I start by going over the reasons of why my previous laser blasters couldn't burn things from far away. In order to do long distance burning, I needed something with higher beam quality/smaller emitter size. I settled on a 1W 405nm laser diode. It is significantly less powerful than my 200W laser bazooka, but the high quality beam it makes can travel much straighter than those huge diode arrays. A single spatial mode laser diode wasn't enough though. I built a beam expander (just a Galilean telescope i
