| Abstract(in English) | We have proposed a Cs optical atomic clock, which generates a standard microwave clock signal with an optical pulse. The clock source uses a regenerative mode-locked fiber laser (MLFL) as a microwave oscillator and an optically pumped Cs gas cell as a frequency standard. In this report, the output pulse width was shortened from 7.1 to 3.4 ps by employing a phase modulator instead of an intensity modulator as a mode-locker. The optical frequency stability for an averaging time of 100 s was also improved from 1.8 x 10^<-11> to 6.3 x 10^<-12> by precisely controlling the laser cavity temperature. |
