Abstract

Recently, a simple common-path, two-color interferometer has been used for Doppler-free saturated dispersion spectroscopy of iodine. We have used such a set-up to stabilize a Nd:YAG laser for the first time, to our knowledge. This method requires only a small number of low-cost optical components compared to frequency modulation techniques. We have measured a root Allan variance of 5·10-12 for 0.2 s, and below 5·10-11 for integration times up to 300 s.
