Laser is the acronym for” light amplification by stimulated emission of radiation” and is different from normal light in the sense that every ray in the beam follows the exactly same direction and path while in normal light beam; the direction of some of the rays may be different. As more and more rays follow the exact same path, the beam becomes more and more concentrated and the diameter is very small. This means that in a laser a lot of energy is concentrated in a single beam that it can be used for cutting and drilling. Laser light is monochromatic, that is, it only has one wavelength beams in it. In the case of normal light, it consists of various wavelengths and this is evident when normal light splits it shows a spectrum of seven colors.
