Progress toward a dual-beam 3D-cooled atom interferometer gyroscope

Abstract

Translate Article

Atom interferometers make use of the interference of matter waves for precise measurement of motion. Employing 3D-laser-cooled atoms provides improved fringe contrast, while measuring in a continuous beam architecture provides high-bandwidth measurement, error suppression of time-varying signals, and the elimination of measurement dead time. In this paper, we discuss the initial observation of interference signals in a dual-beam, 3D-cooled atomic beam interferometer architecture. Additionally, we perform initial characterization of the response of the atom interferometer signal to laser intensity and frequency noise.
