Direct Frequency Comb Measurements of Absolute Optical Frequencies and Population Transfer Dynamics

Abstract

A phase stabilized femtosecond laser comb is directly used for high resolution spectroscopy and absolute optical frequency measurements of one and two photon transitions in laser cooled ^u87 Rb atoms. Absolute atomic transition frequencies, such as the 5S1/2uF=2 7S 1/2uF= 2 two-photon resonance measured at 788 794 768 921 (44) kHz, are determined without a priori knowledge about their values. Detailed dynamics of population transfer driven by a sequence of pulses are uncovered and taken into account for the measurement of the 5P states via resonantly enhanced two-photon transitions.
