In physics,a laser is a device that emits light through a specific mechanism for which the term laser is an acronym:light amplification by stimulated emission of radiation.This is a combined quantum-mechanical and thermodynamical process discussed in more detail below.As a light source,a laser can have various properties,depending on the purpose for which it is designed.A typical laser emits light in a narrow,low divergence beam and with a well-defined wavelength (corresponding to a particular color if the laser is operating in the visible spectrum).This is in contrast to a light source such as the incandescent light bulb,which emits into a large solid angle and over a wide spectrum of wavelength.These properties can be summarized in the term coherence.
