Abstract
A system for magnetic detection includes a magneto-optical defect center material comprising a plurality of magneto-optical defect centers, a radio frequency (RF) excitation source, an optical detector, and an optical light source. The RF excitation source is configured to provide RF excitation to the material. The optical detector is configured to receive an optical signal emitted by the material. The optical light source includes a readout optical light source configured to provide optical excitation to the material to transition relevant magneto-optical defect center electrons to excited spin states in the material, and a reset optical light source configured to provide optical light to the material to reset spin states in the material to a ground state. The reset optical light source provides a higher power light than the readout optical light source.
