Abstract

A method has been developed for the stabilization of an internal mirror He–Ne laser to achieve a high frequency reproducibility that is mainly influenced by the temperature of the stabilized laser. However, it is difficult to achieve a reproducible temperature in a short time under different ambient temperatures. In this paper, the He–Ne laser is stabilized based on the relationship between the laser mode number and the laser cavity temperature where a reproducible temperature can be rapidly achieved under different ambient temperatures, resulting in a high frequency reproducibility. Experiments have demonstrated that the He–Ne laser used can be stabilized in approximately 10 min, typically 6 min; the frequency stability is less than $2\times {10}^{-10}$; the frequency reproducibility is less than $1\times {10}^{-9}$.
