Multibeam atom laser: Coherent atom beam splitting from a single far-detuned laser

Dugue, J; Dennis, Graham; Jeppesen, M; Johnsson, Mattias; Figl, Cristina; Robins, Nicholas; Close, John


We report the experimental realization of a multibeam atom laser. A single continuous atom laser is outcoupled from a Bose-Einstein condensate via an optical Raman transition. The atom laser is subsequently split into up to five atomic beams with slightly different momenta, resulting in multiple, nearly copropagating, coherent beams which could be of use in interferometric experiments. The splitting process itself is a realization of Bragg diffraction, driven by each of the optical Raman laser...[Show more]
