CPM非稳腔Nd:YAG激光器稳定性的探讨

Research on the Stability of Nd:YAG Laser with the CPM Unstable Resonator

本文通过多种因素的理论分析与计算认为光束在CPM非稳腔中传输时同时存在着会聚球面波与发散球面波,证明了发散球面波的传输是稳定的。找到了与稳定条件有关参数的关系式,根据这些参数得到了激光稳定输出的CPM非稳腔。

By the theoretical analyze and calc. lation of the many factors, we consider that when the light beam propagates in the CPM unstable resonator the both convergent and divergent spherical waves simultaneously exist, the latter is proved to be stable in the paper. Found the relation between the parameters according to the stable conditon, the CPM unstable resonator having the stable laser output have been obtained with these parameters.
