We study the linear stark effect of a single nitrogen vacancy center in diamond (NV). The unique properties of the NV allow optical detection of magnetic resonance (ODMR). We use the spin of a single NV as a nano scale electric field sensor. Using pulsed experiments long coherence times are reached, such that the phase difference induced by an alternating electric field can be detected. We reached shot noise limited detection of the electric field. The nano scale sensing of electric fields has a wide range of applications in biology and material sciences.
