热效应对固体激光器偏振特性和基模输出特性的影响
Influence of Thermal Effects on Polarizability and Output Character of TEM00-Mode of Solid State Laser
摘要
分析了固体激光器中两种主要的热效应：热致双折射效应和热透镜效应。对于这些效应在固体激光器中表现出来的退偏效应、热透镜双焦效应和热透镜球差效应, 以及它们对固体激光器基模输出功率的影响进行了分析。并通过4f成像系统和石英旋光器, 对激光棒截面上所有各点进行点对点的补偿, 消除了退偏效应。
Abstract
Two main thermal effects, thermal birefringence and thermal lens effect, are introduced. The depolarization, thermal bifocal lens and thermal lens aberration effects in solid state laser and their influences on output power of TEM00-mode are analyzed. Using the 4f imaging system and silicon rotator for point-to-point compensation of laser rod cross section, depolarization effects are compensated and mitigated.
