Abstract
The interference measurement using the femtosecond optical frequency comb (FOFC) is in progress at present. We analyzed the temporal coherence function (TCF) of an FOFC since which is the fundamental description of the interference phenomenon. As a result, it has been understood that the same high coherence peak exists during the time which is equal to the repetitions interval in the traveling direction of the FOFC. The theoretical derivation has been used to model the TCF of an FOFC and shows good agreement with experimental measurements which is taken with a combination of an ordinary Michelson interferometer and an unbalanced optical-path Michelson interferometer.
