Abstract

In high power polarized TEM00-mode laser diode(LD) side-pumped NdYAG laser resonator, thermal birefringence is the main factor influencing the output power of the polarized TEM00-mode. By using the construction of two NdYAG rods in laser resonator, depolarization effects caused by thermal birefringence have been compensated effectively. After analyzing the influences of the resonator parameters on the laser output performance and optimizing the laser resonator, 35 W polarized TEM00-mode output power is obtained.
