A researcher in optical physics whose team helped connect ultrafast lasers with precision frequency measurement. Their 2000 experiment stabilized the carrier-envelope phase of pulses from a mode-locked laser, controlling the absolute positions of the resulting optical frequency comb. This allowed optical frequencies to be measured against a stable microwave clock.[ref]
