my new this old i can find millions lasers like that not all the lasers must cut somthing my lasers nice and making photons without destroy something. good for cities , expiriments and some electronics and dont forget the tehnolegy
hey my laser close to real http://en.wikipedia.org/wiki/Laser_construction the pump source is the empty place (the photons move faster ther so they dont die) the laser medium is the glow and the optical resonator is the border
You right in that a laser doesn't have to cut something, however a laser is a concentrated beam of light. Light Amplification by Stimulated Emission of Radiation.
I'm going to try to make a laser like the one in the wikipedia article you linked to....
