Frequency stabilization of internal-mirror He-Ne lasers by air cooling

摘要：

　　Instead of traditional heating method,the cavity length of an internal-mirror He-Ne laser is controlled by air cooling which is generated by a mini cooling fan.A PID servo controlling system is designed to drive the cooling fan tuning the frequency of the laser.The frequency is stabilized by balancing the power of two operating longitudinal modes.Beating with an iodine stabilized He-Ne laser,a relative uncertainty( Δf f ) of 4.3×10-9 in 5 months,a frequency fluctuation of less than 2.6 MHz and an Allan deviation of 3×10-11 (τ=100 s) in 75 h are obtained.
