Hi, my name is John, I have a few questions I have to ask before trying to construct a laser for a school project. I fully understand the operation of lasers so non of that has to be re- explained to me. 1. What type of laser(gas) makes a green beam? 2. How much power would it take for a laser to burn through a business card(or so) with a single pulse. 3. I was reading about this laser 'gun' that made a short intense laser pulse and charged for 30 seconds!, i thought capacitors only charged for millionths on a second, please explain why this is so.
