What are the applications and significances of these types of lasers?

Question

I did an experiment with a red laser (about 630nm), a yellow laser (about 590 nm) and a green laser (about 530 nm).

What are the applications of each of these lasers' specifically and what kind of applications do they have?

Answer 1

I can give you a couple of examples, but if these are not enough don't worry about the 10 points. For the red laser they are typically used for pointing devices and to troubleshoot short length fiber optic cables. If the fiber cable has a break then you will be able to see the red laser light being emitted. They can also be used as military weapons (basically to blind people). All those wavelengths can be used as motion sensor detectors. Common applications of the green and yellow (and red) lasers are light displays such as the ones used at concerts. They are also used for cutting guides on circular saws and laser levels. Red mainly.
