Abstract

The results of an experimental comparison of the parameters of the coherent population trapping (CPT) resonance for the 87Rb D1 line and the light shifts during the detection of signals from different cross-sectional areas of the interaction of laser radiation with atoms are presented. A method is proposed to search for zero-light-shift operating conditions and their automatic stabilization, which would improve the long-term stability of CPT-resonance-based microwave frequency standards.
