Abstract
An optical frequency comb is built by using a commercial femtosecond laser and signal-noise (S/N) ratio of the fceo signal is obtained to be about 30 dB. Its repetition rate frequency and offset frequency are highly stable and the tracking stability is verified. An absolute frequency measurement of a 1064 nm Nd: YAG laser is realized by using this stabilized optical frequency comb. The tracking stability of the repetition rate frequency is superior to 3.710-14 at 100 s and the absolute frequency of the laser is 281630111757362 Hz. The experimental result is in accordance with the recommended value by International Committee of Weights Measures(CIPM).
