A device that converts input power into a very narrow, intense beam of coherent visible or infrared radiation.  3, record 1, English, - laser

A laser is a maser which operates at optical frequencies. It is a device which produces an intense beam of visible or infrared coherent light by pumping atoms to ever higher energy levels and allowing them to oscillate in an optical resonator until the energy level is high enough that a constant stream of photons is emitted.  4, record 1, English, - laser

Some prefer the term "optical maser," in which the letter "m" stands for "molecular" instead of its originally assigned denotation of "microwave." While this viewpoint is logical, ... the word "laser" ... has the virtue of brevity and has won popular acceptance.  2, record 1, English, - laser

láser : La Fundación del Español Urgente(Fundéu BBVA), con el asesoramiento de la Real Academia Española, indica que "láser" es la adaptación al español del acrónimo inglés "laser"("light amplification by stimulated emission of radiation" o "amplificación de luz por emisión estimulada de radiación") y lleva tilde en la "a" por tratarse de una palabra llana acabada en una consonante distinta de "n" y "s"; el plural de "el láser" es "los láseres", no "los láser", "los lásers" ni "los lasers".  4, record 1, Spanish, - l%C3%A1ser

[...] LASER est l'acronyme de «Light Amplification by Stimulated Emission of Radiation», ce qui signifie en français : «amplification de la lumière par émission stimulée de radiations». Pour être plus explicite, disons que le laser est [un procédé qui génère] des faisceaux lumineux concentrés (cohérence spatiale) qui présentent la particularité d'avoir tous la même longueur d'onde et d'être tous en phase à un instant donné (cohérence temporelle). La cohérence temporelle permet d'obtenir un faisceau lumineux monochromatique, c'est-à-dire d'une seule couleur (une seule longueur d'onde), tandis que la cohérence spatiale produit un faisceau rectiligne dont l'énergie peut être transportée sur une longue distance sans rien perdre de sa puissance.  1, record 2, French, - amplification%20de%20la%20lumi%C3%A8re%20par%20%C3%A9mission%20stimul%C3%A9e%20de%20radiations
