    "abstract": "We analyse the extraction of a coherent atomic beam from a trapped\nBose-Einstein condensate using a rf transition to a non-trapping state at T=0\nK. Our quantum treatment fully takes gravity into account but neglects all\ninteractions in the free falling beam. We obtain an analytical expression of\nthe output rate and of the wave function of the extracted beam, i.e. the output\nmode of the ``atom laser\u0027\u0027. Our model reproduces satisfactorily experimental\ndata without any adjustable parameter.",
