Data Sheet
An output coupler is a partially reflecting dielectric mirror used in a laser cavity. It transmits a part of the circulating intracavity power for generating a useful output from the laser. A low transmission output coupler leads to a low laser threshold, but also possibly to poor laser efficiency if ...
