| 摘 要： | 实验观察到外腔式He-Ne激光器由于增益管的应力双折射效应而呈现复杂的偏振特性.对几种典型的增益管的应力双折射相移进行了理论分析和实验测量.在增益管端口的增透片上施加适当的径向压力可获得单一的线偏振光输出.

Polarization characteristics of external cavity He-Ne lasers |
| |
| Abstract: | Experimental evidence shows the polarization characteristics of the external cavity He-Ne lasers to be determined mainly by the birefringence of the gas discharge tube.Measuring and theoretical analysis on birefringence of several typical tubes have been carried out.Single-mode linear polarization output can be obtained by means of exerting a suitable radial mechanical pressure to the window plate of the gas discharge tube. |
