quote:Originally posted by QuantumcatI remember studying lasers two years ago in physics ...And Tom you asked if you can see laser light if it is intensified, and the answer is no, because light from something you're seeing has to enter your eyes. Laser light is in a perfect straight line, so none enters your eyes and you can't see it. You can see the dot on the thing you're aiming it at because the light is splayed off so it can enter your eyes. If you can see a laser beam it is because it is a crappy laser, and a lot of the light doesn't go in a straight line like it should, instead splays out immediately and that can enter your eyes. also sometimes the light will bounce of air particles and you can see the light that is bounced off.
