Abstract:

This research program is concerned with matter-wave interferometry of laser cooled atoms. A slow beam of laser cooled rubidium atoms will be used as the matter-wave source. The atom optical elements are microfabricated amplitude transmission gratings which will be used in a three-grating interferometer to split and recombine the rubidium beam. The atomic interferometer will be a useful new tool with which to perform precision experiments in atomic physics, quantum optics, and gravitation. The research program takes advantage of three new technologies, the combination of which provides a unique opportunity to construct a compact and stable interferometer. The techniques of laser cooling and trapping are used to produce cold rubidium atoms in a well-collimated beam. Commercially available diode lasers with optical feedback frequency stabilization are used for the laser cooling and trapping beams and for atomic beam diagnostics. Finally, submicron transmission gratings made with high- resolution electron-beam lithography are used as the coherent beam splitters of the atomic interferometer.
