Phonon cooling and lasing with nitrogen-vacancy centers in diamond [PDF]

Physical Review B, 2013
We investigate the strain-induced coupling between a nitrogen-vacancy impurity and a resonant vibrational mode of a diamond nanoresonator. We show that under near-resonant laser excitation of the electronic states of the impurity, this coupling can modify the state of the resonator and either cool the resonator close to the vibrational ground state or ...

Photoluminescence of nitrogen-vacancy and silicon-vacancy color centers in phosphorus-doped diamond at room and higher temperatures

, 2021
Phosphorus-doped diamond is relevant for applications in sensing,optoelectronics and quantum photonics, since the unique optical properties of color centers in diamond can be combined with the n-type conductivity attained by the inclusion of phosphorus.

Divergent effects of laser irradiation on ensembles of nitrogen-vacancy centers in bulk and nano-diamonds: implications for biosensing

, 2021
Ensembles of negatively charged nitrogen vacancy centers (NV-) in diamond have been proposed for sensing of magnetic fields and paramagnetic agents, and as a source of spin-order for the hyperpolarization of nuclei in magnetic resonance applications.

Nitrogen-Terminated Diamond Surface for Nanoscale NMR by Shallow Nitrogen-Vacancy Centers

, 2019
The nitrogen-vacancy (NV) center in diamond is the most promising candidate for quantum sensing because of its beneficial properties. For quantum-sensing applications, a shallow NV center is critical for approximating the sensing target on a diamond ...

Two-beam coupling by nitrogen-vacancy centers in diamond [PDF]

Optics Letters, 1992
A new method for two-beam coupling measurements based on acousto-optic modulation with subhertz tuning capability is applied to study excited-state dynamics of the nitrogen-vacancy center in diamond. Results yield fundamental decay constants and the nonlinear refractive index and are in good agreement with the calculated dual grating response to ...
