Abstract: We study the optical loading of a trapped Bose-Einstein condensate by spontaneous emission of atoms in excited electronic state in the boson accumulation regime. We generalize the previous simplified analysis of Cirac and Lewenstein ( Phys. Rev. A , 53 (1996) 2466), to a 3D case in which more than one trap level of the excited-state trap is considered. By solving the corresponding quantum many-body master equation, we demonstrate that also for this general situation the photon reabsorption can help to increase the condensate fraction. Such effect could be employed to realize a continuous atom laser, and to overcome condensate losses.
