Abstract
An analysis is presented of the high resolution Autler-Townes spectra in a pump-probe cascade 5S1/2(F=3)→5P3/2(F'=4) → 5D5/2(F") experiment in a working 85Rb-MOT. It is shown that despite the complex nature of the spatially varying interactions of individual atoms with MOT fields, the probed region of the atomic cloud in MOT can be characterized by effective Rabi frequency, at least for the customary used range of detuning and intensity of the trapping field. This effective value which relates to the averaged atom interactions, is directly dependent on the trapping laser power and practically does not depend of detuning. The applied procedure is based on predictions of a three-level model. The procedure can be used as a method for determination of the effective Rabi frequency experienced by atoms in MOT, and it also indicates applicability limits of the approach for a given MOT implementation.
