摘要：
We present a study of the identified for the first time effect of electromagnetically-induced transparency delay in Rb vapours on the atomic clock transition. The effect consists in the presence of a delay in the time of the maximal total transmission of atomic vapour relative to the moment when a two-photon resonance is reached as the frequency difference between two laser fields (FDLF) deviates around the clock transition frequency. It was found out that the delay is higher for higher frequencies of the FDLF modulation and is accompanied by substantial evolution of the width and shape of the coherent population trapping resonance.
