Abstract
We present a scheme for a laser-like source of atoms, starting from at omic de Broglie wave resonators, for which we seek to overcome losses by gain. The resonators are blue-detuned optical dipole-force traps, w hich can be loaded continuously or repetitively with laser-cooled atom s. This is achieved by trapping the atoms in a different internal stat e than that used for laser cooling. The transfer of cold atoms into th e trapped states involves emission of a photon and can be stimulated b y the presence of identical bosonic atoms in the final atomic state. N umerical simulations show threshold behaviour, mode competition and Po issonian atom statistics above threshold.
