The Development of Optical Frequency Measurement

Optical frequency standards are orders of magnitude better frequency accuracy than current microwave atomic standards suitable for frequency standards. The building of optical frequency standard is a great promotion for advance of science and technology in our country and other countries. Measurement of optical frequency standard occupies a important place in the building of optical frequency standard and became a highlight in recent years. So the dey point is the measuring method. A review of optical frequency standard is present in this paper, including the traditional measuring method, the measurements of the optical frequency standard with femtosecond mode-locked laser and the new development of the optical frequency standard measurements.
