We report a study of thermally induced depolarisation of a laser beam in single cubic syngony crystals of 23 and m3 symmetry groups with an anisotropic elastic stiffness tensor. For active elements in the form of a long rod and a thin disk with radial cooling under uniform volume pumping, we investigate the effect of anisotropy of elastic properties on the dependence of the degree of depolarisation in the crystal on the orientation of the crystallographic axes, as well as on the position of the critical orientation in the crystallographic coordinate system.

弹性各向异性对径向冷却单立方同晶中激光束热致畸变的影响。第三部分

我们报告了对具有各向异性弹性刚度张量的 23 和 m3 对称群的单立方同心晶体中激光束的热致去极化的研究。对于在均匀体积泵送下具有径向冷却的长杆和薄盘形式的活性元件，我们研究了弹性各向异性对晶体中去极化程度对晶轴取向的依赖性的影响，以及晶体坐标系中临界取向的位置。
