A semi–classical model is derived for describing the interaction between coherent electromagnetic radiation and a Bose–Einstein condensate in the limit of zero temperature, including the back action of the atoms on the radiation. This model is used to analyze the problem of the self–consistent evolution of a laser beam and a BEC atomic beam. The mutual propagation is studied numerically and demonstrates the possibility of a stationary regime of mutual guiding, but also of generating a collapse– like phenomenon.
