Wow, looks very nice like on many Hollywood's films, I like it and I want to see these weapons soon.

Lasers all work in pretty much the same way: Excite certain kinds of atoms, and light particles-photons-radiate out. Reflect that light back into the excited atoms, and more photons appear. But unlike with a lightbulb, which glows in every direction, this second batch of photons travels only in one direction and in lockstep with the first. And instead of shining in every part of the spectrum, laser light is all the same wavelength, which depends on the â€gain mediumâ€-the type of atoms-you use to generate the beam. Shine enough of the focused light, and things start to burn.
