This is Shalom EO’s 127-001 output coupler. This Plano-plano Circular partially reflective laser mirror, with Dia12.7mmxT3mm dimension, based on dielectric coatings and N-BK7 substrates, usually placed inside the laser cavities in application, is designed for extracting 532 nm laser beams from Nd:YAG Laser cavities and resonators. The first surface is coated with T=10±2%@532nm PR coating, and the back surface is coated with AR@532nm, T>99.8% to deliver 90R/10T for the design wavelength. The output coupler is engineered to be used at 0° angle of incidence.
