We supply our customers with laser cavity output couplers, with custom coatings, substrate materials and dimensions available upon request. The front surface of the output coupler is partially reflective over a range of wavelengths, while the rear surface is anti-reflective to prevent Fresnel reflection losses. More importantly, these laser cavity output couplers can be successfully implemented as fixed-ratio laser power attenuators for specific wavelength ranges.

1. Mirror substrate made of high quality UV grade fused silica; 2. Select 50%~99% reflectivity in the most popular wavelength range;
The output coupler is used to stabilize the laser resonator to emit part of the energy circulating in the laser cavity.
