Hey, we're not gonna call each other names here, just because you can't understand how simple things work. So, why don't I explain it for you. LASERS are a form of LIGHT that is concentrated in a COHERENT, UNIFORM direction and wavelength. WAVELENGTH explains COLOR. You can make them using something called a MACHINE. A DEVICE. Do you need that explained to you as well?
