2012 2013-05-27T08:08:32Z We describe an all-optical scheme for spin manipulation in the ground-state triplet of the negatively charged nitrogen-vacancy (NV) center in diamond. Virtual optical excitation from the <sup>3</sup>A<sub>2</sub> ground state into the <sup>3</sup>E excited state allows for spin rotations by virtue of the spin-spin interaction in the two-fold orbitally degenerate excited state. We derive an effective Hamiltonian for optically induced spin-flip transitions within the ground state spin triplet due to off-resonant optical pumping. Furthermore, we investigate the spin qubit formed by the Zeeman sublevels with spin projection m<sub>S</sub>=0 and m<sub>S</sub>=−1 along the NV axis around the ground state level anticrossing with regard to full optical control of the electron spin.
