Abstract

We demonstrate a compact light-pulse atom interferometer (LPAI) with a high data-rate grating magneto-optical trap (GMOT) and a photonic-integrated-circuit (PIC)-compatible laser system. These efforts are aligned with one of our primary goals, LPAI operation in high-dynamic environments through ruggedization and miniaturization of the sensor head and laser systems. The compact sensor head is based on a custom vacuum package and a grating chip with fixed optical components. The high data-rate LPAI operation with a GMOT enables the operation of LPAIs in high dynamics. PIC-compatible and PIC-based laser systems are realized and used to demonstrate LPAIs towards miniature cold-atom inertial sensors.
