We present a compact and integrated optically pumped atomic magnetometer (OPM) developed for high-sensitivity biomedical applications. This device, based on a Spin-Exchange Relaxation-Free (SERF) atomic magnetometer configuration, demonstrates a sensitivity of 20 fT/√Hz with a bandwidth of 1 to 80 Hz. The miniaturization of the magnetometer is achieved through the integration of an...

We report on the progress of implementing an atomic magnetometer based on free spin precession using our in-house manufactured rubidium-87 MEMS (micro-electromechanical systems) vapor cells. The magnetometer employs a pulsed pump and probe laser scheme, featuring a double pass through the vapor cell configuration for the probe laser beam. The magnetometer currently exhibits a sensitivity of...

Optically-pumped magnetometers (OPM) using metastable helium-4 species allow real-time, space-resolved vector measurement of magnetic fields at room temperature. Moreover, the bandwidth of this kind of sensors --up to 2 kHz-- covers the whole emission of the human brain. Hence, this technology proves very promising for magnetoencephalography (MEG) applications while minimizing patient...
