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 × 10 12 for τ = 1 s and 8.8 × 10 14 for τ = 100 s for a 9.1926 GHz microwave output signal.
