|Abstract:||To suppress the Dick effect, one of the main limitations of short-term frequency stability for pulsed atomic clocks, the interleaving lock technique is applied to eliminate the dead time. In this paper, we demonstrate the technique in a pulsed Ramsey-coherent population trapping clock with two identical Cs atomic ensembles. The measured short-term frequency stability is improved from 1.3×10?11 at 1 s to 3.0×10?12 at 1 s, and part of the Allan deviation curve exhibits 1/?0.96 slope.|
