Abstract

Variable reflectivity output mirrors (VRM) provide good possibility for output coupling of diffraction limited beams both from gas and solid state laser media. A set of different VRM resonators was designed and tested in fast- transverse and fast-axial-flow CO₂ lasers. It was shown that the phase profile of the output beam in VRM resonator may be improved by the appropriate design of the VRM output coupler. The results of experimental and theoretical studies of stable and unstable VRM resonators operation in CW CO₂ lasers with output power up to 3 kW are presented.
