摘要

We demonstrate a new approach to designing a compact RF standard based on the transfer of frequency stability of hyperfine transitions in molecular iodine to the stability of a laser cavity length. We use frequency doubled Nd:YVO_4 laser operating in Kerr lens mode-locked regime and frequency lock it to hyperfine transitions in molecular iodine with further detecting the beat note signal between longitudinal modes on a fast photodiode. A similar system is used for estimating the standard Allan deviation of RF signal which is 2.1 × 10~(14) at the time 100 s.
