A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The fir ...
that does not rely on a large population of photons within the laser cavity to maintain
coherence.
Rather than relying on photons to store phase coherence, it relies on collective effects in an atomic medium to store coherence. Such a laser uses repumped Dicke
superradiance
In physics, superradiance is the radiation enhancement effects in several contexts including quantum mechanics, astrophysics and relativity.

In quantum optics, superradiance is a phenomenon that occurs when a group of ''N'' emit ...
(or superfluorescence) to sustain emission of light that can have a substantially narrower linewidth than a conventional laser.
