Abstract
One example embodiment includes an atomic sensor system. The system includes a magnetic field generator configured to generate a magnetic field in a volume. The system also includes a vapor cell arranged within the volume and comprising a polarized alkali metal vapor. The system further includes at least one magnetic field trimming system configured to generate a magnetic field gradient within the vapor cell separate from the magnetic field to provide a substantially uniform collective magnetic field within the vapor cell.
