摘要：

A common-path two-colour interferometer is proposed for the detection of sub-Doppler saturated dispersion resonances of molecular iodine with no modulation on the laser beam. Hyperfine components of the R(56)32-0 line have been observed with a high signal-to-noise ratio by using a Nd:YAG laser. The observed signals of the dispersion resonance, the background of which has a small dependence on the optical geometry, will be used for laser frequency stabilization.
