Compensation of depolarization loss in solid-state lasers

The depolarization loss induced by heat generated in solid-state lasers was described.Then a new oscillator to compensate depolarization loss was introduced to eliminate influence on the laser output because of the depolarization.No evident change of laser shape or energy per pulse was observed along with changing repetition frequency from 20Hz to 50Hz.At 50Hz with 9.6J injection electrical energy,111.24mJ@1064nm dynamic output was obtained,the electric-optic efficiency reached 1.16% with stabilization of ±1.85%.Good compensation can be seen evidently with this new configure.
