Аннотация:
The authors have studied the behaviour of an optical hole in the <sup>3</sup>A to <sup>3</sup>E zero-phonon absorption of the nitrogen-vacancy centre in type 1b diamond under the influence of an externally applied magnetic field. Spin cross relaxation and level anti-crossing phenomena in the <sup>3</sup>A ground state are displayed as sudden reductions of the optical hole depth (hole-bleaching) for specific orientations and strengths of the applied magnetic field.
