Sažetak
We present direct observation of the velocity-selective optical pumping of the Cs ground state hyperfine levels induced by the fem¬ ; ; ; tosecond (fs) laser oscillator centered at either D2 (6 2S1/2→ 6 2P3/2, 852 nm) or D1 (6 2S1/2→ 6 2P1/2, 894 nm) cesium line. We utilized previously developed modifi ed direct frequency comb spectroscopy (DFCS) which uses a fi xed frequency comb for the excitation and a weak cw scanning probe laser centered at the 133Cs 6 2S1/2→ 6 2P3/2 transition (D2 line) for ground levels population monitoring. The frequency comb excitation changes the usual Doppler absorption profi le into a specific periodic, comblike structure. The mechanism of the velocity selective population transfer between the Cs ground state hyperfi ne levels induced by fs pulse train excitation is verified in a theoretical treatment of the multilevel atomic system subjected to a pulse train resonant field interaction.
