A probe beam is passed through a first optically pumped magnetometer vapor cell portion that has a first magnetic bias field orientation relative to a pump beam. The probe beam is also passed through a second optically pumped magnetometer vapor cell portion that has a second magnetic bias field orientation relative to the pump beam with the same properties as in the first portion, where the first magnetic bias field orientation is opposite to that of the second magnetic bias field orientation. This configuration reduces or eliminates linearly polarized magnetic signals (e.g., noise) from the output probe beam and passes circularly polarized magnetic signals. Thus, the intensity of the probe beam after passing through the first and second optically pumped magnetometer vapor cell portions is measured to obtain a noise suppressed signal.
