Abstract
In this paper we report on the Ti:Sapphire mode-locked femtosecond laser based optical frequency comb apparatus and developed by NIM its application in optical frequency measurement of the I2 stabilized 532 nm Nd:YAG laser installed in NIM. The measurement result of 127I2 R (56) 32-10 hyperflne transition is 563260223512991 ±20 (Hz), with a relative frequency uncertainty of 3.6 × 10-14. To our knowledge, this result is the first optical frequency measurement in China which is referenced directly to the Cs microwave frequency standard.
