Device that produces an intense beam of coherent light (light composed of waves having a constant difference in phase). Its name, an acronym derived from "light amplification by stimulated emission of radiation," describes how its beam is produced. The first laser, constructed in 1960 by Theodore Maiman born 1927 based on earlier work by Charles H. Townes, used a rod of ruby. Light of a suitable wavelength from a flashlight excited (see excitation) the ruby atoms to higher energy levels. The excited atoms decayed swiftly to slightly lower energies (through phonon reactions) and then fell more slowly to the ground state, emitting light at a specific wavelength. The light tended to bounce back and forth between the polished ends of the rod, stimulating further emission. The laser has found valuable applications in microsurgery, compact-disc players, communications, and holography, as well as for drilling holes in hard materials, alignment in tunnel drilling, long-distance measurement, and mapping fine details; Light Amplification by Stimulated Emission of Radiation This phenomenon is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation in the visible region Lasers operate in the visible, infrared, or ultraviolet regions of the spectrum They are capable of producing immense heat and power when focused at close range and are used in surgical procedures, in diagnosis, and in physiologic studies [MeSH, 1965]; An acronym for light amplification by stimulated emission of radiation A medical instrument that produces a powerful beam of light and can produce intense heat or cool vaporization when focused at close range Lasers are often used in surgery to remove tissue; abbr Light Amplification by Stimulated Emission of Radiation; An acronym of Light Amplification by Stimulated Emission of Radiation A laser is a cavity that has mirrors at the ends and is filled with lasable material such as crystal, glass, liquid, gas, or dye These materials must have atoms, ions, or molecules capable of being excited to a metastable state by light, electric discharge, or other stimulus The transition from this metastable state back to the normal ground state is accompanied by the emission of photons which form a coherent beam; Light Amplification by Stimulated Emission of Radiation A device that produces coherent light with a narrow range of wavelengths; Light Amplification by Stimulated Emission of Radiation Light Amplification by Stimulated Emission of Radiation; An acronym for light amplification by stimulated emission of radiation; Light Amplification by Stimulated Emission of Radiation generates monochromatic, coherent light, usually from an excited gas or semiconductor; an acronym for light amplification by stimulated emission of radiation A device that uses stimulated emissions to produce a coherent beam of electromagnetic radiation; Light Amplification by Stimulated Emission of Radiation; The acronym for Light Amplification by Stimulated Emission of Radiation A laser is an intense beam with very narrow band width that can produce images by electronic impulses from digital data; A laser is a narrow beam of concentrated light produced by a special machine.
