多横模内腔He—Ne激光器的特殊偏振现象

SPECIAL POLARIZATION PHENOMENON OF MULTI-TRASVERSE MODE INTERNAL-MIRROR He-Ne LASER

我们观察到了多横模内腔He-Ne激光器的一些特殊偏振现象。根据激光器的兰姆理论,分析了简并模的退简并问题,对退简并模之间的频差进行了测量,并对观察到的现象做了理论分析。

We have observed some special polarization phenomenon of multi-transverse mode He-Ne laser. Elimination problem of mode degeneration was analysed based on Lamb theory of laser. Frequency difference between degenerate mode after eliminating degeneration was measured, and the observed phenomena were analysed theoretically.
