Claims18
A process for enhancing sensitivity in measuring spin state in nitrogen vacancy (NV) centers in a diamond sample, the process comprising applying an optical excitation radiation to a diamond having at least one nitrogen vacancy (NV) center, the radiation comprising light having a wavelength between 400 and 638 nm, illuminating the sample with light having a wavelength between 700 and 1042 nm, and detecting, measuring and/or counting photons emitted from the at least one NV center.
A process for enhancing sensitivity in measuring spin state in nitrogen vacancy (NV) centers in a diamond sample, the process comprising:
- irradiating a diamond having at least one nitrogen vacancy (NV) center with a light having a wavelength between 400 and 638 nm, to thereby excite the NV centers,
- irradiating the diamond with a light having a wavelength between 700 and 1042 nm, and
- detecting photons emitted from the at least one NV centers, at wavelengths ranging between 700 and 1050 nm.
A device comprising a diamond sample comprising at least one nitrogen vacancy (NV) center, a first illumination source configured and operable to illuminate the diamond sample at a wavelength in a spectral range between 400 and 638 nm, a photon counter, and a second illumination source configured and operable to illuminate the diamond sample at a wavelength in a spectral range between 700 and 1042 nm.
A magnetometer device comprising a diamond having at least one nitrogen vacancy (NV) center comprising one or more electronic spins, wherein the electronic spins are configured to align with the diamond crystallographic axis in response to optical excitation radiation applied to the at least one NV center;
- and a photon counter configured to detect output optical radiation at the IR range correlated with the electronic spins when subjected to an optical enhancement.
