Abstract
Optical gain in an amplifier based on NV-colour centres (CC) in diamond is proposed as a new method for optical magnetic field detection. An analytical expression for magnetic field sensitivity with this method is deduced. The sensitivity is highest at the pump intensities about 100 times above the saturation intensity of NV-CC and can reach values of ~1.4 fT (√Hz)−1 in a pump-probe configuration with an NV-CC concentration in diamond of 2.5 ppm. Collection efficiency of probe emission can be simpler and significantly higher than that of NV-CC luminescence, used for conventional optical magnetometry in diamond. This makes this method attractive for applications requiring remote magnetic field sensing.
