Large-area Atom Interferometric Sensors using Excited-Band Bloch Oscillations
Abstract
(Approved for Public Release) Large area atom interferometers provide excellent sensitivity to inertial forces and are thus of great importance for navigation. By utilizing Bloch oscillations in excited bands of an optical lattice operated at #magic# depths, we have recently unlocked a promising new method to scale up atom interferometer area without compromising its phase stability, thus enhancing its sensitivity. Applying this magic depth tool within our Yb atom interferometry apparatus, we propose to demonstrate phase-stable operation with interferometer arm momentum separation approaching one thousand photon recoils which corresponds to 4centimeters spatial separation in only 10milliseconds. In addition to setting new benchmarks for atom interferometry with pulsed standing waves, this can lead to improving the state-of-the-art in inertial sensing by more than an order of magnitude.
