Abstract
Variable reflectivity output mirros (VRM) provide a good possibility for output coupling of diffraction limited beams both from gas and solid state laser media. A set of VRM resonators was designed and tested in fast-transverse-flow CO2 laser. 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 unstable VRM resonators operation in CW CO2 lasers with output power up to 3 kW are presented. It was shown that beam generated in VRM unstable resonator may be characterized correctly in terms of M2 and K factors.
