Nitrogen-vacancy (NV) centers in Diamond are a promising platform for quantum technological realizations. We investigate hybrid quantum systems based on a NV-center coupled to a vibrating structure which is also a light resonator (cavity). The NV center interacts with the strain field associated to a high Q vibrational mode of the structure and with the cavity photon field. The mechanical resonator and the cavity also interact via radiation pressure coupling. We discuss the cooling dynamics of the mechanical resonator in these settings. The cooling regime, the stationary temperatures, the cooling rate, and the resonance fluorescence spectrum are theoretically evaluated. The features associated with the cooling dynamics are identified in the spectrum of resonance fluorescence.
