Description
Laser Output Couplers are optical components used to transmit a portion of the circulating intracavity power from a laser, generating a useful output beam. These couplers play a crucial role in laser performance, as their transmission level affects the laser threshold and efficiency.
By selecting the appropriate output coupler transmission, laser designers can optimize output power while considering other design requirements, such as minimizing intracavity intensities or suppressing Q-switching instabilities in mode-locked lasers.
