Coherent atom optics with an atom laser

Abstract : Atom laser beams which are extracted from Bose-Einstein condensates of dilute atomic vapor are coherent matter wave sources with extraordinary properties. We report on the measurement of the temporal coherence of such an atom laser beam. The freely falling matter wave beam is retro-reflected by a magnetic mirror which leads to an overlap between the incident and the reflected wave. The resulting interference pattern is recorded by a novel magnetic resonance imaging technique with a resolution of 65 nm in free space. From the contrast of the interference pattern we find that the linewidth of the atom laser beam is Fourier-limited by its temporal duration. For the use of atom lasers in precision experiments such as atom interferometers we have devised atom optical elements, such as a mirror, a beam splitter, and a resonator. Moreover, we have demonstrated a continuous, state selective detection scheme for the atom laser beam.
