Abstract
A magnetometer system structured to measure a magnetic field. The device may comprise a housing with shock absorbers disposed within and a laser cavity network disposed within the housing. The laser cavity network may comprise one or more laser cavity arms, each having a gain chip configured to generate a laser beam and a means for locking a wavelength of the laser beam. The laser cavity network may further comprise a nitrogen-vacancy (NV) diamond disposed within the laser cavity network, configured to accept the one or more laser beams of the one or more laser cavity arms and measure the magnetic field in response to the plurality of laser beams. The system may further comprise a power and control subsystem communicatively connected to the laser cavity network such that the power and control subsystem is external to the housing.
