Phys. Rev. Lett. 95, 023001 (2005) [4 pages]Direct Frequency Comb Measurements of Absolute Optical Frequencies and Population Transfer DynamicsReceived 12 March 2005; published 6 July 2005 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 87Rb atoms. Absolute atomic transition frequencies, such as the 5S1/2 F=2→7S1/2 F′′=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. © 2005 The American Physical Society URL:
