Laser is an abbreviation for light amplification by stimulated emission of radiation. A laser is a device that releases a beam of coherent light through an optical amplification process. There are many types of lasers including solid state lasers, gas lasers, fiber lasers, dye lasers and diode lasers. A laser beam is created when the electrons in atoms in special crystals, glasses or gases absorb energy from an electrical current and become active. Laser light is different from normal light ...
