Phys. Rev. A 62, 043604 (2000) [6 pages]Loading a continuous-wave atom laser by optical pumping techniquesReceived 17 April 2000; published 12 September 2000 Demonstrating that, despite loss processes, Bose-Einstein condensates can be formed in steady state is a prerequisite for obtaining a coherent beam of atoms in a continuous-wave atom laser. In this paper we propose a method for loading atoms into the thermal component of a Bose condensed cloud confined in a magnetic trap. This method is aimed at allowing steady-state dynamics to be achieved. The proposed scheme involves loading atoms into the conservative magnetic potential using the spontaneous emission of photons. We show that the probability for the reabsorption of these photons may be small. © 2000 The American Physical Society URL:
