Coherent backscattering of intense laser light by cold Sr atoms - a diagrammatic pump-probe approach — •Andreas Ketterer, Vyacheslav Shatokhin, and Andreas Buchleitner — Physikalisches Institut Albert-Ludwigs-Universität Freiburg, Germany

The diagrammatic pump-probe approach is a promising method to study coherent transport of intense laser light in cold atomic clouds [1]. It expresses the multiple scattering signal in terms of single atom responses, and thus avoids the problem of the exponential growth of the Hilbert space dimension with an increasing number of atoms. In this talk we will show how to construct arbitrary single-atom building blocks for atoms with internal degeneracy, and present numerical results for triple scattering from Sr atoms.
