Nd:YAG Laser Output Couplers SKU: 031-0095
Laser Output Couplers 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 the losses due to output coupling do not…
