晶体石英置于He-Ne激光谐振腔中,由于双折射效应,会产生激光频率分裂。本文报道了频率分裂量与光线光轴夹角的非线性关系及对此现象的研究,实验结果表明频率分裂曲线与石英族光性曲线有对应关系,即旋光性是一个影响频率分裂的因素。

Because of the birefrinsence effect, when a quartz plate is placed in a He-Ne cavity, the phenomenon of mode splitting will occur. This peper reports the nonlinear relation between the quantity of mode splitting and the angle between a laser ham and optical axis of a quartz plate. Experiment is done, showins that the optical activity is a factor which influences mode splitting.
