Question

What is the full meaning of LASER

Answer 1

The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".It is a device that generates an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules. Lasers are used in drilling and cutting, alignment and guidance, and in surgery; the optical properties are exploited in holography, reading barcodes, and in recording and playing compact discs.
