Windeler AB - 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.
