excitation dependence of Resonance Line self broadening at different atomic densities
Journal of Physics B, 2009Co-Authors: Hebin Li, Vladimir A Sautenkov, Yuri V Rostovtsev, Marlan O ScullyAbstract:We study the dipole?dipole spectral broadening of a Resonance Line at high atomic densities when the self-broadening dominates. The selective reflection spectrum of a weak probe beam from the interface of the cell window and rubidium vapour is recorded in the presence of a far-detuned pump beam. The excitation due to the pump reduces the self-broadening. We found that the self-broadening reduction dependence on the pump power is atomic density independent. These results provide experimental evidence for the disordered exciton based theory of self-broadening, and can be useful for the description of the interaction of a strong optical field with a dense Resonance medium.

nonLinear Resonance Line shapes dependence on the transverse intensity distribution of a light beam
Physical Review A, 2004Co-Authors: A V Taichenachev, A M Tumaikin, V I Yudin, M Stahler, R Wynands, John KitchingAbstract:We analyze the Line shape and width of atomic coherent-population-trapping (CPT) Resonances excited by laser beams with different transverse intensity profiles. A dramatic difference in the Resonance Line shape is found when comparing a beam with a 'steplike' profile to a beam with a Gaussian profile. In particular, for nonuniform profiles, a non-Lorentzian functional form is given that is more appropriate for describing the nonLinear Resonance Line shape than is a conventional Lorentzian. Our analysis is supported by measurements of CPT Line shapes in a thermal vapor of {sup 85}Rb.
