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.
PACS numbers: 32.80.-t, 39.30.+w, 32.80.Qk, 39.25.+k
Phase-stabilized optical frequency combs based on
mode-locked femtosecond lasers have formed a power-
ful connection between the fields of precision measure-
ment and ultrafast science [1, 2, 3]. Numerous applica-
tions have ensued, including measurements of absolute
optical frequencies [4, 5, 6] and the development of op-
tical atomic clocks [7, 8, 9]. Recent work has demon-
strated that optical frequency combs are a highly efficient
tool for precise studies of atomic structure [10, 11]. Di-
rect frequency comb spectroscopy (DFCS) has been per-
formed on the 5S-5D two-photon transitions in Rb, per-
mitting high-resolution spectroscopy of all atomic transi-
tions covered by the comb bandwidth. Additionally, this
approach provides significant advantages for precise stud-
ies of time domain dynamics, coherent accumulation and
interference, and quantum control [11]. An extension of
