Abstract
We report on pulsed-laser induced and solid-immersion lens (SIL) assisted generation of nitrogen-vacancy centers (NVs) in diamond. The NVs are characterized by a narrow distribution of the optical transition linewidth peaked around 50 MHz. This includes the effect of long-term spectral diffusion caused by a necessary repump green laser. Such high-quality NVs are excellent candidates for practical implementations employing two-photon quantum interference with separate NV centers. The perspective of implementation of these NVs in open microcavities will be discussed.
