Abstract :
We report on accuracy test results on the comparison of two different types of optical frequency combs, each of those referenced to a microwave frequency standard and an optical frequency standard. One of those combs is based on a mode-locked erbium-doped fiber laser and the other is based on a Ti:sapphire femtosecond laser. The comb comparison was carried out by measuring an absolute frequency of an acetylene-stabilized diode laser with both combs simultaneously.
