laser

Also known as light amplification by stimulated emission of radiation, lasers

dispositivo que emite luz através de amplificação ótica

AI overview

A laser is a device that produces an intense, focused beam of light by stimulating atoms or molecules to emit radiation in a coherent way. Lasers matter because they have practical applications across many fields—in this case, they're being used as guide stars to help telescopes see more clearly through the atmosphere.

Um laser (acrônimo inglês para light amplification by stimulated emission of radiation, ou seja, amplificação de luz por emissão estimulada de radiação), em português láser ou lêiser, é um dispositivo que produz radiação eletromagnética com características muito especiais: ela é monocromática (possui comprimento de onda muito bem definido), coerente (todos os fótons que compõem o feixe emitido estão em fase) e colimada (propaga-se como um feixe de ondas praticamente paralelas).
