    "abstract": "A phase-stabilized femtosecond laser comb is directly used for\nhigh-resolution spectroscopy and absolute optical frequency measurements of\none- and two-photon transitions in laser-cooled \\rb atoms. Absolute atomic\ntransition frequencies, such as the 5S$_{1/2}$ F=2 \\ra 7S$_{1/2}$ F\"=2\ntwo-photon resonance measured at 788 794 768 921(44) kHz, are determined\nwithout \\textit{a priori} knowledge about their values. Detailed dynamics of\npopulation transfer driven by a sequence of pulses are uncovered and taken into\naccount for the measurement of the 5P states via resonantly enhanced two-photon\ntransitions.",
