Advances in Dynamic Range and Coherence of Continuous Cold-Atom Interferometers
Abstract
NRL has recently developed a unique capability of continuous, 3D-cooled atomic beam interferometry. Atom interferometers have historically suffered from low dynamic range as compared to classical sensors. Additionally, difficulties arise with maintaining coherence in the interferometric process when performing continuous, cold-atom interferometry. Here we employ our new atom interferometer architecture to address the issue of low dynamic range by ramping the velocity of a continuous atomic beam in order to infer the unambiguous absolute phase of an atom interferometer. Additionally, we will discuss techniques to characterize and improve on the coherence in our continuous, cold-atom interferometer.
