Output Coupler transmits a part of the circulating intracavity power for generating a useful output from the laser.
A low transmis sion output coupler leads to a low laser threshold, but also possibly to poor laser efficiency if the losses due to output coupling do not dominate over other parasitic losses in the laser cavity. We produce high quality Laser Output Couplers.
We can customize according to customer's requirements.
■ Advantages of Output Coupler:
•Radiused components with tight centration tolerances
•Tight tolerances on reflectivity
•Low loss and scatter
•Exceptional plasma durability
