By spanning an optical octave ( 300 THz) with a broadened femtosecond laser frequency comb, we directly measure the frequencies of optical standards at 1064/532 nm, 633 nm and 778 nm in terms of the microwave frequency that controls the comb spacing. This microwave frequency can be linked directly to the cesium standard. Index Terms-Frequency measurement, laser stability, optical frequency conversion, optical spectroscopy.
