Abstract :
We demonstrate a new approach to designing a compact RF standard based on longitudinal mode beating. We use frequency doubled Nd:YVO4 laser operating in mode-locked regime stabilized to hyperfine transitions in molecular iodine. 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.
