10 April 1995Continuous wave high-power solid state laser with VRM output coupler
In this paper, the dynamic characteristics of Gaussian resonators with thermal lensing is analyzed and a novel resonator-stable resonators with Gaussian reflectivity mirrors (GRMSR) is introduced. CW lasers with designed Gaussian stable resonator radiates laser beam with output power 200 W and beam parameters 6.2 mm mrad. For Gaussian resonators, the near field shows more uniform distribution and the far field shows lower diffraction rings than those of plane-plane stable resonators.
