Optical properties of the nitrogen-vacancy singlet levels in diamond
We report measurements of the optical properties of the 1042 nm transition of negatively charged nitrogen-vacancy (NV) centers in type-1b diamond. The results indicate that the upper level of this transition couples to the ${m}_{s}=\ifmmode\pm\else\textpm\fi{}1$ sublevels of the $^{3}E$ excited state and is short lived with a lifetime of $\ensuremath{\lesssim}1\text{ …
