Coherent inelastic backscattering of laser light from three isotropic atoms

Published Nov 20, 2014• 7 citations

Abstract

We study the impact of double- and triple-scattering contributions on coherent backscattering of laser light from saturated isotropic atoms in the helicity-preserving polarization channel. By using the recently proposed diagrammatic pump-probe approach, we analytically derive single-atom spectral responses to a classical polychromatic driving field, combine them self-consistently to double- and triple-scattering processes, and numerically deduce the corresponding elastic and inelastic spectra, as well as the total backscattered intensities. We find that accounting for the triple-scattering contribution leads to a faster decay of phase-coherence with increasing saturation of the atomic transition as compared with double scattering alone and to a better agreement with the experiment on strontium atoms.

Rigorous derivation of the triple scattering signal from single-atom responses

Vyacheslav Shatokhin, Thomas Wellens

We study coherent backscattering of intense laser light from three immobile two-level atoms using the master-equation approach. The master equation is solved analytically, and the triple scattering spectrum is expressed in quadratures. We show that this solution can be obtained via a self-consistent combination of single-atom spectral responses, and is equivalent to the solution following from the diagrammatic pump-probe approach. We deduce the general expressions for single-atom building blocks which can be used in simulations of multiple inelastic scattering of laser light in the bulk atomic medium.

Diagrammatic treatment of coherent backscattering of intense light by cold atoms with degenerate energy levels

We present a generalization of the diagrammatic pump-probe approach to coherent backscattering (CBS) of intense laser light for atoms with degenerate energy levels. We employ this approach for a characterization of the double-scattering signal from optically pumped atoms with the transition ${J}_{g}\ensuremath{\rightarrow}{J}_{e}={J}_{g}+1$ in the helicity-preserving polarization channel. We show that, in the saturation regime, the internal degeneracy becomes manifest for atoms with ${J}_{g}\ensuremath{\ge}1$, leading to a faster decrease of the CBS enhancement factor with increasing saturation parameter than in the nondegenerate case.

Elastic versus inelastic coherent backscattering of laser light by cold atoms: A master-equation treatment

Vyacheslav Shatokhin, Cord Axel Müller, Andreas Buchleitner

We give a detailed derivation of the master-equation description of the coherent backscattering of laser light by cold atoms. In particular, our formalism accounts for the nonperturbative nonlinear response of the atoms when the injected intensity saturates the atomic transition. Explicit expressions are given for total and elastic backscattering intensities in the different polarization channels, for the simplest nontrivial multiple-scattering scenario of intense laser light multiply scattering from two randomly placed atoms.

Spectrum of coherent backscattering of light by two atoms

V. N. Shatokhin

The inelastic spectrum of coherent backscattering of laser light by two atoms was theoretically studied. For an intense laser field, there are frequency domains of either constructive or destructive self-interference of inelastically scattered photons. The emergent spectral features were interpreted by considering coherent backscattering as a pump-probe experiment.
