氦-氖激光器的偏振特性

Polarization properties of He-Ne lasers

本文简述了全内腔He-Ne激光器输出光束的偏振特性,分析了影响其偏振特性的主要原因和偏振“弹回”对仪器使用的影响,介绍了获得线偏振激光束的几种He—Ne激光器的结构。还介绍了用横向磁场实现全内腔He-Ne激光器线偏振的优点。

In this paper,the polarization properties of output beams of internal mirror He-Ne laser is simply described. The main causes which effects the polari zation properties and the influencs of polarization flip on the use of instrument are analysed. The construction of several types of He-Ne lasers obtained linear polarization of laser beams is introduced. The advantages of realizing the linear porization of internal mirror He-Ne lasers by a strong transverse magnetic field are also pointed out,
