Abstract

We report direct measurement of population dynamics in the excited state manifold of a nitrogen-vacancy center in diamond. We quantify the phonon-induced mixing rate and demonstrate that mixing can be completely suppressed at low temperatures. Further, we measure the intersystem crossing (ISC) rate for different excited states and develop a theoretical model that unifies the phonon-induced mixing and ISC mechanisms. We find excellent agreement between our model and experiment, and discuss the model's implications for enhancing the NV center's performance as a room-temperature sensor.
