    "abstract": "Coherent population trapping is demonstrated in single nitrogen-vacancy\ncenters in diamond under optical excitation. For sufficient excitation power,\nthe fluorescence intensity drops almost to the background level when the laser\nmodulation frequency matches the 2.88 GHz splitting of the ground states. The\nresults are well described theoretically by a four-level model, allowing the\nrelative transition strengths to be determined for individual centers. The\nresults show that all-optical control of single spins is possible in diamond.",
