A scanning optical quantum magnetometer with submicron spatial resolution is proposed. It is based on the physical phenomenon of hole burning in an optically detected magnetic resonance (ODMR) signal. This signal has been registered on spin colour centers of atomic size in silicon carbide under conditions of a saturation of spin levels by additional high-frequency resonance pumping. The increase in sensitivity is due to the narrowing of the ODMR line and an increase in the slope of the dependence of the signal frequency on the magnetic field.
