Scope note: Fuente óptica que emite fotones en un haz coherente. La amplificación de la luz por emisión estimulada de radiación (LASER- siglas en inglés)) se produce mediante dispositivos que transforman la luz de diversas frecuencias en un haz único intenso, casi no divergente, de radiación monocromática. Los láseres operan en las regiones del infrarrojo, luz visible, ultravioleta o de rayos X del espectro.

Scope note: An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.
