摘　　要：介绍了利用兰姆凹陷稳频He-Ne激光器的基本结构与腔长调节工作方式,从激光器结构方面对影响其预热时间、频率稳定度和频率重复性的主要因素进行了深入探讨。介绍改进设计的新型微晶玻璃腔体一体化兰姆凹陷稳频He-Ne激光器的基本结构、制作工艺与优势。该激光器腔体采用极低膨胀系数的微晶玻璃材料,反射镜采用石英镜片光胶连接,无应力超高真空铟封形式,谐振腔稳定性好。利用该激光器进行了实验,实验结果表明,该激光器工作中不需要预热,环境适应能力极强,在高低温与冲击振动条件下均能稳定工作,频率稳定度可以达到10-10量级。The basic structure of traditional Lamb-dip stabilized He-Ne laser and its cavity length controlling manner are introduced. The influence of the laser′s structure on its warm-up time, frequency stability and reproducibility is discussed in detail. The basic structure and techniques of a novel-type integrated Lamb-dip stabilized He-Ne laser are presented, whose cavity with very low coefficient of expansion is made of zerodur. There are noticeable techniques applied in the laser, including the quartz reflective mirrors′ optical contact and the super high vacuum indium seal, that ensure the cavity′s steady operation and its frequency high stability. The experimental result shows that the laser is able to operate well without warm-up time, even though in the condition of either high-low temperature or shocking environment, whose relative frequency stability can reach the order of magnitude of 10-10.
