Cold and Continuous Atom Interferometer with Advanced Sensing Techniques

We present new measurements of a continuous atomic interferometer designed for inertial sensing. The interferometer is derived from an atom source which emits a continuous beam of sub-Doppler cooled atoms while simultaneously mitigating near-resonant scattered light. Enabled by the unique properties of the atom source, the derived interferometer demonstrates continuous measurement exhibiting high contrast and low noise. We describe and characterize the concept of rapid switching of intertial sensitivity, much faster than the characteristic time-scale of a typical matter-wave interferometer, including a noise analysis and comparison with traditional methods Our work here inspires future cold-atom architectures which can measure with both high sensitivity and high bandwidth.
