A pumped atom laser

Abstract

We present the experimental realization of a pumped atom laser. We demonstrate the pumping through measurements of the source and laser-mode atom numbers, making a rate equation study of the pumping process.

Version 2 contains 18 pages and 4 figures. We have significantly rewritten the introduction, as well as including a discussion of Rayleigh and Raman superradiant scattering and how these relate to continuous pumping of an atom laser. Five new references were added
