Lamb-Dip Frequency-Stabilized He-Ne Laser With an Integrated Cavity Made of Zerodur (Ⅰ): Structure and Techniques
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.
