Continuous Atom Laser and Atom Interferometry in a Magnetic Atom Guide
Abstract
The objective was to realize a phase- and amplitude-stable, coherent atomic beam. The completed setup allows one to achieve this goal and contains: (1) a Zeeman slower as a primary cold-atom source, (2) a relay magneto-optic trap that collects and cools the atoms, (3) a pusher beam that transfers the atoms in bunches into a (4) magneto-optic injection device, (5) a 1.7m long magnetic atom guide section for continuous evaporative cooling, (6) a condensation and atomic-beam extraction region at the end of the guide, and (7) provisions to perform atom interferometry. Component (4) adiabatically compresses atoms and releases them into (5); it also includes a mechanical atomic-beam shutter for optical insulation of laser-cooling light from the magnetic-guiding section. In (5), the cold-atom flow is continuously cooled via surface adsorption on 21 silicon strips. Final status: Construction of all components and laser systems is complete. Components (1) - (3) have been experimentally tested. The components (4) - (7), while being ready to use, will require considerable human resources for continued work. The project has included a component on photo-ionization, Rydberg atom evolution, and spatially resolved ion detection in magnetic guides as an analytic method for position-resolved BEC and cold-atom imaging. The work on Rydberg guiding and ion detection is complete.
