摘要：

The output of a mode-locked femtosecond laser is used for precision single-photon spectroscopy of Cs-133 in an atomic beam. By changing the laser's repetition rate, the cesium D-1 (6s S-2(1/2) -> 6P P-2(1/2)) and D-2 (6s S-2(1/2) -> 6p P-2(3/2)) transitions are detected and the optical frequencies are measured with accuracy similar to that obtained with a cw laser. Control of the femtosecond laser repetition rate by use of the atomic fluorescence is also implemented, thus realizing a simple cesium optical clock.
