Phys. Rev. A 81, 013626 (2010) [5 pages]Loading atom lasers by collectivity-enhanced optical pumpingReceived 4 November 2009; published 27 January 2010 The effect of collectivity on the loading of an atom laser via optical pumping is discussed. In our model, atoms in a beam are laser-excited and subsequently spontaneously decay into a trapping state. We consider the case of sufficiently high particle density in the beam such that the spontaneous emission is modified by the particle interaction. We show that the collective effects lead to a better population of the trapping state over a wide range of system parameters, and that the second-order correlation function of the atoms can be controlled by the applied laser field. © 2010 The American Physical Society URL:
