Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed a Cs optical atomic clock, which carries a atandard microwave clock signal with an optical pulse. The clock source uses a regenerative mode-locked fiber laser (MLFL) as a microwave oscillator and a Cs beam tube or 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.
