摘　　要：本文报导了用激光频率分裂技术实现的全内腔和半内腔应力双折射双频激光器。这两种激光器输出的频差可通过调节加在激光器应力双折射元件上的压力调节 ,调节范围可从几十 MHz到几百 MHz。激光器经预热后 ,两种激光器输出频差的相对变化分别为 10 - 3和 10 - 5。Two kinds of novel dual-frequency He-Ne lasers and presented are described in this paper based on the birefringent laser frequency splitting technology:the full-inner cavity and the half-inner cavity photoelastic dual-frequency lasers.The frequency difference between the two kinds of dual-frequency He-Ne lasers can be adjusted from tens to hundreds of MHz by adjusting the mechanical pressure exerted on the photoelastic element.The stability of the frequency differences of the two lasers are 10 -3 and 10 -5,respectively,after the lasers are turned on for while.
