Based on the polarization properties of the corner-cube, polarized coupling output is obtained in the electro-optically Q-switch solid state laser with corner-cube resonator. The laser is operated in the heatconducted half-circular LD arrays pumped Nd : YAG laser,and produces the average pulse energy of 163mJ at 20 Hz in a 6. 5 ns pulse with an optical-to-optical conversion efficiency of 16. 7%. The energy stability is of ±2.8% ,and the beam divergence is of 3.5 mrad. The performance of the laser is much better than that in plane-parallel resonator such as the high efficiency, high peak power,controllable pulse energy and width,and high stability.
