Abstract :
Optical double-frequency phase comparator is proposed for detection of sub-Doppler saturated dispersion resonances of the OsO/sub 4/-absorber. This technique exhibits high sensitivity and small dependence of the background on the optical geometry. Experimental comparison of the phase resonances with normal Lamb-dip is presented.
