Paper Abstract

A novel high average power double slab laser with hybrid resonator is presented. By analyzing and simulating thermal distribution of the face-pumped slab medium, it is found that the thermal distortion of wave front caused by the non-uniform temperature distribution of the laser gain media can be self-corrected in this structure. According to the analysis of the slab thermal distribution, a hybrid resonator is presented. Using a plane-wave or k-space expansion together with the fast Fourier transform, mode patterns, power outputs from the laser are calculated. Far-field characteristic and beam quality of these modes are discussed. And besides, by comparing the properties of off-axis hybrid resonator with the on-axis hybrid resonator's, the off-axis hybrid resonator can produce better quality beam.
