lasing medium
The material that produces stimulated emission from within a laser oscillator. Laser gain media may vary from extended-length glass fibers to submicron-length semiconductor material.
lasing threshold
The lowest excitation power level at which a laser's output is mainly the result of stimulated emission rather than spontaneous emission.

lasing medium
The material that produces stimulated emission from within a laser oscillator. Laser gain media may vary from extended-length glass fibers to submicron-length semiconductor material.
laser active elements
Laser active elements typically refers to the substances or materials within a laser system that play a critical role in the amplification of light through the process of stimulated emission. These...
laser head
Contains elements which produce lasing., e.g. gain medium, oscillator mirrors as well as housing.
laser materials processing
Laser materials processing refers to a diverse set of manufacturing techniques that utilize lasers to modify, cut, weld, drill, or otherwise manipulate materials. These techniques offer high...
laser output
The laser output refers to the generated and emitted light produced by a laser system. This output is characterized by several key properties that distinguish lasers from other light sources. These...
laser rod
In a solid-state laser, the material (Nd:YAG, Nd:glass, ruby) in which lasing action takes place.
laser surgery
Laser surgery refers to a medical procedure in which a laser, or focused beam of light, is used as a precision tool to cut, vaporize, coagulate, or otherwise modify tissues for therapeutic or...
liquid laser
A laser that uses a substance in the liquid state, such as an organic dye, as the active lasing medium.
