Investigation of the TEM00-Mode Output Character from LD Side-Pumped Two Nd:YAG Rods in Laser Resonator
摘要
在高功率线偏振基模输出激光二极管(LD)侧面抽运NdYAG激光腔中,热致双折射效应是影响线偏振基模输出功率的主要热效应。利用双棒串接结构,对热致双折射效应引起的退偏效应进行了有效的补偿。在分析谐振腔参数对激光器性能影响的基础上,通过优化设计,在实验中得到了35 W的线偏振基模输出。
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.
