(a) ODMR spectrum of electron spin at B=507 Gauss. (b) Pulse sequence to manipulate electron and nuclear spins at ESLAC. (c) ODMR spectrum and (d) Rabi oscillation of the nearby 13C nuclear spin. At ESLAC, electron spin and nearby nuclear spins (including host 14N nuclear spin and nearby 13C nuclear spins) can be polarized by a short laser pulse. Then spin states are manipulated by resonant MW or RF pulses. Electron spin states are readout by counting the fluorescence intensity of NV centre; nuclear spin states are mapped to electron spin and readout in the same way. The resonant frequency of this nuclear spin is 495 kHz, which is slightly modified by centre electron spin.
