Abstract
A magnetometer device structured to measure a magnetic field while minimizing an effect of vibration on output. The device may comprise a laser cavity network containing a plurality of spatially-distinct cavity arms, each comprising a gain chip configured to generate a laser beam towards one or more optical elements disposed optically in line with the laser beam, configured to direct the laser beam towards a nitrogen vacancy (NV) diamond. The device may further comprise the NV diamond, configured to accept a plurality of laser beams of the plurality of cavity arms without a common output coupler, preventing the plurality of laser beams from spatially overlapping, and measure the magnetic field in response to the plurality of laser beams. The device may further comprise a reflective element for reflecting each laser beam back into each cavity arm.
