SERF magnetometer array using concurrent amplitude-stabilized optical modulation

Alexandria Engineering Journal
We demonstrate a compact atomic magnetometer array that uses concurrent amplitude-stabilized optical modulation (CASOM) to improve the low-frequency performance and long-term stability for bio-magnetic measurements.

Buffer Gas Pressure Optimization for Atomic Spin Relaxation Suppression in Ultra-High-Sensitivity SERF Magnetometers

Photonics
Optically pumped magnetometers (OPM) are core quantum payloads for geomagnetic remote sensing. Among them, the spin-exchange relaxation-free (SERF) OPM with aT-level ultimate sensitivity stands as mainstream.

Single-beam three-axis SERF atomic magnetometer based on coordinate system rotation

Optics Express
We propose what we believe to be a new single-beam three-axis spin exchange relaxation free (SERF) vector atomic magnetometer scheme based on coordinate system deflection. A theoretical model for the system response under arbitrary angle deflection was established for the first time, and the system response at different angles was simulated and ...
