Full Form of LASER
Light Amplification by Stimulated Emission of Radiation
LASER Full Form is Light Amplification by Stimulated Emission of Radiation. Lasers work through resonance effects and the output is a consistent electromagnetic field. In other words, in such a beam of coherent electromagnetic energy, the frequency, and phase of all the waves are same. LASER also refers to the device that generates the beam of intense light. This light is produced through a process known as optical amplification.
LASER evolved originally from MASER (Microwave Amplification by Stimulated Emission of Radiation) which is a form of radio waves and microwaves with no visible light. It was Gordon Gould; a town student discovered the light form of MASER, which brought LASER into existence in 1957. LASER is used in laser printers, cutting and welding tools, optical disk drives, laser surgery, barcode scanners, and various scientific researches.
