laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; … Universalium
Coherence (physics) — In physics, coherence is a property of waves that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the correlation between physical quantities of a wave. When… … Wikipedia
Laser safety — A typical laser warning symbol. Laser safety is safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to… … Wikipedia
Coherence length — In physics, coherence length is the propagation distance from a coherent source to a point where an electromagnetic wave (or wave packet, wave function, etc.) maintains a specified degree of coherence. The significance is that interference will… … Wikipedia
