To anyone who cares, for my next project I want to try my hand at building my own cutting laser. I don't mean the cheap DVD player/mini-mag flashlight light matches and pop balloons thing. I want to use it to cut sheet metal and spot weld. I would be greatly appreciative to anyone who could direct me where to look. Is it possible to take a laser that is moderately powerful and mae it more powerful? Maybe a 1000mW laser? Can someone please help me with this?
