Abstract

Absorption spectra of cold Cs atoms in a magneto-optical trap under the influence of a strong external pump laser field with arbitrary detuning and intensity have been systematically investigated. The spectra featured the Rabi sidebands of each transition, and their behavior was nicely fitted by the dressed-atom theory. A pronounced dispersion-type profile with sub-natural linewidth at the pump frequency may be attributable to the stimulated Raman process by sublevels that are lightshifted and optically pumped by the pump laser.

  8. When Bloch equations are solved for a strong pump beam and a weak probe beam, 9 or in a more elaborate treatment as in Ref. 10, a small dispersion-type structure appears at Δ=0. In Fig. 4 we simply neglect this structure. In fact, as we see below, the stimulated Raman contribution is dominant compared with this structure.
