Abstract: A diamond can be used in a magnetometer to determine the strength of a magnetic field applied to the diamond. The diamond includes a first portion comprising a plurality of nitrogen vacancy (NV) centers dispersed throughout the first portion. The diamond also includes a second portion adjacent to the first portion. The second portion does not contain NV centers. The second portion is configured to facilitate transmission of light generated by the NV centers of the first portion away from the first portion.

Abstract: A system for magnetic detection includes a housing including a top plate, bottom plate, side plate, and main plate provided between the side plate and the bottom plate; a magneto-optical defect center material including at least one magneto-optical defect center that emits an optical signal when excited by an excitation light; a radio frequency (RF) exciter system configured to provide RF excitation to the magneto-optical defect center material; an optical light source configured to direct the excitation light to the magneto-optical defect center material; and an optical detector configured to receive the optical signal emitted by the magneto-optical defect center material. The elements of the system are mounted to the main plate and capable of being unattached and remounted to the main plate to change at least one of a location or an angle of incidence of the excitation light on the magneto-optical defect center material

Abstract: A sensor is described comprising a waveplate assembly, an optical excitation source and a magneto-optical defect center material with defect centers in some embodiments. The waveplate assembly can include a waveplate, mounting base, and a mounting disk. The mounting disk can be adhered to the waveplate. The mounting base can be configured such that the mounting disk can rotate relative to the mounting base around an axis of the waveplate. The waveplate can be used to tune the magnetic field measurement for certain axes materials by controlling the polarization of light entering the magneto-optical defect center material or to conduct a calibration of the system.
