Systems And Methods For Increasing The Degree Of Atomic Polarization In Optically Pumped Magnetometers Based On Magnetic Field Zeroing

Abstract

The disclosure describes optically pumped magnetometers and systems incorporating, and methods of operating, the same. An optically pumped magnetometer according to one embodiment of the present technology includes a vapor cell configured to contain an atomic absorber such as rubidium—87, and at least one light source in optical communication with the vapor cell. The optically pumped magnetometer includes components positioned and configured to provide a bias field, and induce a zeroing field, within the vapor cell. Among other useful and advantageous ends, embodiments of the present technology provide for increasing the degree of atomic polarization in optically pumped magnetometers based on zeroing the bias magnetic field during the optical pumping process.
