Laser scanning - Wikipedia

Laser scanning is the controlled deflection of laser beams, visible or invisible. Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners

Scientific Definition of a Laser - ThoughtCo

A laser is a device which is built on the principles of quantum mechanics to create a beam of light where all of the photons are in a coherent state — usually with the same frequency and phase. (Most light sources emit incoherent light, where the phase varies randomly.)

Laser* - alanpedia

Laser* - A device in which an optical cavity is filled with a medium where a population inversion can be produced by some means. When the resonant frequency of the cavity bears the proper relation to the separation of the inverted energy levels, stimulated emission occurs, producing a highly monochromatic, coherent beam of light.

Laser | definition of laser by Medical dictionary

la·ser. 1. (noun) A device that generates an intense, narrow beam of light created by bombarding an active medium (for example, CO 2, Nd:YAG, argon), with energy in the form of high-voltage electricity, high-intensity light, or radio frequency waves. By passing through a mirrored tube, the photons are released as a nondivergent ("collimated ...
