    "abstract": "We present the first calculation of coherent backscattering with inelastic\nscattering by saturated atoms. We consider the scattering of a\nquasi-monochromatic laser pulse by two distant atoms in free space. By\nrestricting ourselves to scattering of two photons, we employ a perturbative\napproach, valid up to second order in the incident laser intensity. The\nbackscattering enhancement factor is found to be smaller than two (after\nexcluding single scattering), indicating a loss of coherence between the doubly\nscattered light emitted by both atoms. Since the undetected photon carries\ninformation about the path of the detected photon, the coherence loss can be\nexplained by a which-path argument, in analogy with a double-slit experiment.",
