Finding the nitrogen-vacancy singlet manifold energy level using charge conversion pulse sequences

Abstract

The vast research conducted on Nitrogen-Vacancy (NV) centers in diamond in recent years opened the door for a wide range of NV based applications. However, some properties of the NV center dynamics and energy levels remain unknown. In this work, we propose a charge conversion pulsed sequence scheme for locating the NV center singlet manifold energy level, by multi-color excitation using a tunable laser. We present two approaches for readout - photo-induced current and NV${}^0$ population - and discuss their efficiency for different regimes in the relevant spectrum.
