本文介绍采用拍频曲线晶振基准法首次在Uniphase 1007型长寿命商品He-Ne激光管上实现了无压电陶瓷调谐元件的塞曼双频稳频,采用可调永磁供磁,达到光频长期漂移5×10^(-9);双频双线偏振分离度1/60;双线偏振正交度89.5°;入锁及锁定情况良好.给出了塞曼双频激光器的调试技术.描述了输出光束偏振状态和纵模数关系的一个物理现象.

The Uniphase 1007 type long lifetime commercil He-Ne laser is studied as Zeeman frequency stabilized laser. A frequency drift of 5 * 10-9 is obtained by the maximum error analysis method for the observation period of 17 hours. The seperation between two linear polarizations of two frequency components of the laser output beam is 1/60. The orthogonal angle between two linear polarizations of the laser beam is 89. 5°. The experimental adjustment technique of Zeeman laser is given. A physical phenomena is discribed on the relationship between polarizations of laser beam and number of longitudinal modes.
