QUANTUM MAGNETOMETER BASED ON DIAMOND LASER Russian patent published in 2024 - IPC G01V3/14 

FIELD: physics.

SUBSTANCE: invention relates to quantum sensorics and can be used in quantum information technologies to measure the value and direction of induction of an external magnetic field. A quantum magnetometer based on a diamond laser contains a solid-state active element in the form of a diamond NV laser with a laser-active element in the form of a diamond sample with a high concentration of substituting nitrogen and with a lower concentration of NV centres by 1-2 orders of magnitude, with varying intensity of laser radiation depending on characteristics of external magnetic field, optical pumping source in the range of phonon absorption wing of NV-centres and electromagnets.

EFFECT: design of a quantum magnetometer based on a diamond NV laser operating on the principle of laser threshold magnetometry.
