Autler-Townes splitting in absorption spectra of the excited states 6 2P3/2 - 8 2S1/2 of cold cesium atoms confined in a magneto-optical trap (MOT) has been observed. Experimental data of the Autler-Townes splitting fit well with the dressed-atom theory, which reflects the fact of the cold atoms dressed by cooling and trapping laser beams. The results of the theoretical fitting with experiment not only told us the effective Rabi frequency cold atoms experienced, but also could be used for measuring the probability amplitudes of the dressed states.
Keywords:Autler-Townes doublet;dressed state;effective Rabi frequency;probability amplitude
