This study presents the effect of optical medium density on the suppression of light field shift in a coherent population trapping resonance excited with multi-component radiation. Experimental and theoretical results both indicate that the suppression of CPT resonance light shift depends on the optical density of the medium.
Presented for the first time are studies of the effect of optical medium density on the possibility of suppression of light field shift of a coherent population trapping (CPT) resonance excited with multi-component radiation generated by modulation of the injection current of a pumping single-frequency diode laser. It is shown experimentally and theoretically that the possibility of suppressing CPT resonance light shift depends on the optical density of the medium.
