We describe the operation and results of our first generation zero field optically pumped magnetometer (OPM) developed for biomedical applications. The OPM technology is one of the most promising non-cryogenic candidates to replace superconducting quantum interference device (SQUID) magnetometers in key areas of biomagnetism. The first-generation sensors are designed to transition OPM technology from a physics laboratory to researchers in the medical community. The laser and optical components are tightly integrated inside the sensor package, and the sensor is tethered to a dedicated electronics signal processing unit that enables automated and standalone operation inside a magnetically shielded room.
