Abstract:
To measure the frequency of a laser, the frequency of a beat signal that is generated by the interference between an optical frequency comb, used as the reference of measurement, and the laser to be measured is measured. In such a laser frequency measurement using the optical frequency comb, at least one of a repetition frequency and a CEO frequency of the optical frequency comb is changed so that the frequency of the beat signal becomes a predetermined value, and the frequency of the beat signal is measured, so that the frequency of the laser is measured. This allows measurement of the frequency of laser having large frequency variation and low stability.

Claim (Index 2):
The laser frequency measurement method using an optical frequency comb according to  claim 1 , comprising the steps of:\n measuring the repetition frequency f rep  and the CEO frequency f CEO ; and changing at least one of the repetition frequency f rep  and the CEO frequency f CEO  such that the frequency of the beat signal becomes the predetermined value.
