摘要：
A lin-par-lin Ramsey-CPT microwave atomic clock with dispersion detection is investigated in this paper, in which high signal contrast and narrow linewidth are obtained. The pulsed transmitted laser is synchronously detected by a sample-and-hold amplifier and a lock-in amplifier. The frequency shift of the microwave, represented by the output of the lock-in amplifier is acquired. An instability is estimated to be 6.6x10(-13) / root tau.
