Abstract

A magnetometer for magnetic detection includes a magneto-optical defect center material having at least one magneto-optical defect center; a radio frequency (RF) exciter system including a radio frequency (RF) excitation source; an optical excitation system including an optical excitation source; an optical detector configured to receive an optical signal based on light emitted by the magneto-optical defect center material due RF excitation and optical excitation provided to the magneto-optical defect center material via the RF excitation source and the optical excitation source, respectively; a magnetic field generator configured to generate a magnetic field detected at the magneto-optical defect center material; and a system controller.
