Abstract
An atomic magnetometer system includes a laser system, a cell, and an optics setup. The laser system is configured to generate a pump beam and a probe beam. The cell encloses an atomic vapor. The optics setup is configured to route the pump beam and the probe beam. The pump beam propagates along a path through the atomic vapor and the probe beam also propagates substantially along the path through the atomic vapor. The pump beam and the probe beam traverse the atomic vapor along two or more non-parallel directions. The interaction of the pump beam with the atomic vapor is modulated at or near harmonics of a magnetic resonance frequency.
