A Compact High Data Rate Grating Magneto-Optical Trap Atom Interferometer

Quantum gravity and inertial sensors based on cold atom interferometry demonstrate exceptional

sensitivity in laboratory settings and are currently being employed for gravity surveys and inertial

sensing through sensor miniaturization and ruggedization. To streamline the cooling beam delivery and

reduce the size of the sensor head for flight vehicles, we employ a grating-magneto optical trap (GMOT)

that uses a single beam instead of six. To enhance sensor robustness against vibrations and dynamic

conditions, high data rate atom interferometry is crucial for minimizing the relative motion between the

atoms and the sensor platform. Following our demonstration of high data rate sub-Doppler cooled

GMOT atoms (10 uK, 150 Hz), we achieved GMOT atom interferometry with a sensitivity of 6 ug/rt-Hz

and a bias stability of 800 ng. Additionally, we characterize and analyze the achievable sensitivity of this

sensor platform as the data rate varies.
