We propose and demonstrate a mode-locked laser-type optical atomic clock with an optically pumped cesium (Cs) gas cell. By adopting the optically pumped Cs gas cell with a double resonance method as a frequency standard, we have successfully demonstrated an ultrastable rack-mount type Cs optical atomic clock with excellent short-term stability. The obtained frequency stabilities reached as high as 1.2 x 10(-12) for tau=1 s and 8.8 x 10(-14) for tau=100 s for a 9.1926 GHz microwave output signal.
我们提出并展示了一种采用光泵浦铯（Cs）气室的锁模激光型光学原子钟。通过采用双共振方法的光泵浦Cs气室作为频率标准，我们成功展示了一种具有出色短期稳定性的超稳定机架式Cs光学原子钟。对于9.1926 GHz微波输出信号，在τ = 1 s时获得的频率稳定性高达1.2×10^(-12)，在τ = 100 s时为8.8×10^(-14)。
