Abstract
We report the experimental details of an optical frequency synthesizer based on a frequency-stabilized femtosecond mode-locked Ti:sapphire laser for absolute optical frequency measurement. The repetition rate frep of the system is 100 MHz and is phase-locked to a Cs atomic clock, and the carrier-envelop-offset (CEO) frequency is phase-locked to a subharmonic of frep (actually to zero) by using a self-referencing technique. As a result, we have established a phase coherent link between a microwave frequency standard and the nth mode of an optical frequency comb by the relation fn = nfrep, where n is an integer. Absolute optical frequency measurements should be straightforward using this new optical frequency synthesizer.
