Thermal effects such as the thermally induced lens and thermally induced birefringence of the laser rod pumped by high power LD in laser amplifier and their compensations were discussed. Minus lenses can make good compensation for the thermally induced lens of the laser rod. The depolarization loss caused by the birefringence is reduced with a 90°quartz rotator and imaging relay optical system between two similar laser modules. Both of the output power and the efficiency of laser are improved in experiment.
