摘要：

We demonstrate a synchronously stimulation method for achieving coherent population beating (CPB) atomic clock with the CPB signal which have continuous wave and higher signal-to-noise ratio. In this method we synchronously apply the coherent population trapping (CPT) resonant stimulating lights together with the detuned detecting lights to obtain continuous CPB oscillation signal. Under the stimulation, the ground state coherence is maintained and the problem of CPB signal decaying is solved, which is beneficial for the measurement accuracy of the CPB frequency and the stability of the clock. The table experimental system of the synchronously stimulated CPB clock has been experimentally implemented and a stability of 7.7x10(-11) at 1 second, 9.6x10(-13) at 1000 second was observed.
