摘　　要：介绍了无源共轴球面腔闭合条件的一般性矩阵表示。针对固体激光器光腔中热透镜效应,利用Matlab符号运算功能,得出热透镜光腔的闭合条件;建立了自行闭合的热稳腔模型,将光腔的闭合条件和热透镜效应模型结合,随着泵浦功率的提高,通过控制微变形镜来自适应改变腔镜曲率半径,进而可以使固体激光谐振腔的输出稳定。Passive coaxial spherical cavity effect in the cavity of solid-state laser, the using symbolic operation of Matlab. The combining the closure condition with the is introduced by using a general matrix. In view of the thermal-lens closure conditions of thermal lens optical cavity was obtained by automatic closed thermal stable cavity model was established, thermal lens effect model of optical cavity. The mirror curvature radius was changed adaptively by controlling the deformable mirror with the increase of pumping power, thus could make the output of resonant cavity of solid-state laser stable.
