Laser output Coupler
Laser output lenses, also known as partially reflective lenses: Laser output lenses are mainly used in resonant cavities to ensure that the laser power and output pattern, part of the energy is reflected into the resonant cavity and the other part is output for cutting, welding and heat treatment. Widely used in CO2 and YAG laser systems.
