Microfabricated Collimators for a Cesium Atom Interferometer GyroscopeNew Submission

Collimated atomic beams sources find important use in applications ranging from fundamental physics investigations to inertial sensors, clocks, and electrometers. Recent progress in microfabricated collimators allow for miniaturization of these devices and narrowing down of the velocity profile. By carefully engineering the velocity profile of the atomic beam coming out of the device, it is possible to make a jet with a narrow velocity spread optimized for a light-pulse atom interferometer, thereby potentially suppressing the background signal and stabilizing the fringe amplitude. We report on microfabricated collimators for cesium ovens with potential applications for atom-interferometer gyroscopes.
