Optical initialization and detection of nitrogen-vacancy(NV) center spin state at room temperature makes NV center system suitable for variety of applications. The dressed state transitions are important for polarization transfer from NV center spin to surrounding spin bath under Hartmann Hahn condition. The resonant and near-resonant field driving for two-level system corresponding to single quantum transition from single NV center ground state is studied. The Autler-Townes effect and Multi-photon processes are observed. The dependence of Autler-Towenes and Multi-photon transitions on strength and detuning of resonant and near-resonant field is studied.The single quantum transition in NV center ground state is good candidate for qubit because simulation performed for bichromatically driven two level-system matches closely with the experimental result.
