Abstract

Through the use of a high-flux rubidium beam source with sub-Doppler temperatures in three dimensions, we have demonstrated an inertially sensitive atom interferometer featuring high contrast, low noise, and continuous measurement with high bandwidth. We describe the cold-atom source and the optical design that optimizes interferometer contrast. Finally, we demonstrate useful features enabled by this architecture, such as continuous phase shear readout and rapid reversal of inertial sensitivity. This demonstration may enable future cold-atom sensors that measure with both high sensitivity and high bandwidth.
