Abstract

We study the dynamics of a magneto-optical trap (MOT) operating at high bandwidth. We find the absolute importance of high recapture efficiency between cycles to maintain a practical atom number. We develop a simple one-dimensional model accounting for MOT trapping forces and pressure-induced collisions and verify with experimental data using ⁸⁷Rb. This is then applied to quantum sensing, predicting a shot noise limited sensitivity of 1×10⁻⁷g/√Hz for a gravimeter at 100 Hz operation. The results are useful for understanding MOT operation at high bandwidth, particularly in the context of developing mobile high-bandwidth quantum inertial sensors targeting dynamic environments and navigation applications.
