i woked at a computer company a few months ago, and a big client of ours was a lasercompany.. as well stated, lasers are lika any other light, composed of energy (fotons) and when thay hit a suface thay ether bounce or getts converted to heat.
the cool thing is that the company hadd large kompressors with air, wich thay blew onto the linses, cooling them down to aprox -70 in about 0.68 secounds.. only with air..
black label delta? 1 0wn y4!
i like one of those kompressors..
