LASERThe acronym LASER stands for Light amplification by stimulated emission of radiation. A laser is a device that produces a unique type of light not found naturally. This light is generated through optical amplification, which relies on the stimulated emission of electromagnetic radiation. It is different from conventional light in three ways. First, the lights from LASER contains only one color or wavelength that is why it is called ‘monochromatic’. Secondly, all the wavelengths are in phase
