含热透镜的非稳腔CPM固体激光器分析

Analysis of CPM Unstable Resonator Solid Laser with Thermal Lens

本文考虑到Nd^(3+):YAG棒在工作中的热效应,把含热透镜的CPM非稳腔等效为平凸空腔,以此分析CPM非稳腔的结构参数对激光器输出能量、光束远场发散角和抗干扰能力的影响,得出的结论与实验相符。

Taking the thermal effect of Nd^(3+): YAG rod in laser operation into account, the authors equate the colliding pulse mode-locking unstable resonator with thermal lens to a plane-convex cavity. Based on which the influences of the stuctural parameters of CPM un- stable resonator on energy ountput, far-field divergenceangle of optical beam, and antijam- ming ability of this solid laser are analysed; and a conclusion in conformity to experiment re- sult is drawn.
