Incoherent laser
WebA laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term is an acronym for light amplification by stimulated emission of radiation. WebTemporal coherence is the ability of light to maintain a constant phase at one point in space at two different times. This essentially follows from the light being monochromatic, and in fact the coherence time τ c is related to the frequency width of the laser light τ c ∝ 1 / Δ f.
