Abstract

The NV system nitrogen vacancy center in diamond is an atom like system which has emerged in recent years as a rich playground for versatile experiments and technologies such as: foundations of quantum mechanics e g entanglement quantum information processing magnetic sensing and so on When probing an ensemble of NVs an inhomogeneous spectroscopic line broadening is introduced which could damage that unique abilities of the NV system We show using a novel Doppler free type spectroscopy that the origin of the inhomogeneous broadening is local magnetic fields within the diamond solid state lattice We also show that this new type of spectroscopy can reduce the inhomogeneous broadening thus exhibiting a narrower linewidth These findings contribute to the understanding of the physics of the NV system and may also improve future technological applications
