LaserFor alternative meanings see laser (disambiguation). A laser light amplification by stimulated emission of radiation is a device which uses a quantum mechanical effect, stimulated emission, to generate a coherent beam of light. Light from a laser is often Laser scienceLaser science is a branch of optics that describes the theory and practice of lasers. Laser science is principally concerned with quantum electronics, the design of optical resonators, the physics of laser media, the temporal evolution of the light field Laser applicationsSoon after the invention of the laser in 1960, it was described as "a solution in search of a problem". However, since that time, the laser has found a place as a useful tool in many scientific, military, medical and industrial applications. Scientific Mo Laser constructionA laser system generally consists of three important parts: An energy source (usually referred to as the pump or pump source ; A gain medium or laser medium A mirror, or system of mirrors, forming an optical resonator. The pump source is the part that pro Laser printerA laser printer is a common type of computer printer that produces good quality printing, and is able to produce graphics. The process is very similar to the type of dry process photocopier first produced by Xerox. Indeed, the first laser printer was crea LaserWriterThe Apple LaserWriter was one the first laser printers available to the mass market. Combined with GUI-based programs like PageMaker on the Macintosh, it is generally considered to have sparked the Desktop publishing (DTP) revolution in the mid-1980s.
