The pump-probe approach to coherent backscattering of intense laser light by atoms with degenerate energy levels — •Ralf Blattmann, Vyacheslav Shatokhin, Thomas Wellens, and Andreas Buchleitner — Physiklisches Institut Freiburg

Recently, we proposed the pump-probe approach to coherent backscattering (CBS) of laser light by cold two level atoms [1,2]. This approach allows to express the double scattering CBS signal in terms of single-atom responses and is a promising tool for a multiple scattering theory of intense laser light from cold atoms. In this talk we will present the generalization of this approach for two atoms with degenerate energy levels and show numerical results for two different atomic transitions.
