quality factor (laser resonator)
spatial mode
Also known as transverse mode. The configurations of energy storage, relative to the structure of a laser resonator, that define the relative intensity distribution of the laser beam.
stable resonator
A laser resonator in which a mode oscillating between the mirrors will converge upon the laser's longitudinal axis.
vertical external cavity surface-emitting laser
A laser that has a surface-emitting semiconductor gain element coupled to an external mirror designed to complete the laser resonator. VECSELs can be electrically or optically pumped. The extended...
