| Abstract(in English) | A regeneratively mode-locked fiber laser can self-oscillate stably without a synthesizer. The laser has jitter less than 100 fs, so that a beat signal obtained between the longitudinal laser modes can be used as an ultra-stable pure microwave signal. By using this laser as an optical microwave oscillator, a new type of Cs optical atomic clock can be composed and have already been confirmed the operation. In this paper, we observed an atomic resonance of Cs (Ramsey fringe) at 9.1926 GHz for the first time with the optical microwave oscillator, and measured the fundamental characteristics of the Cs optical atomic resonance. |
