N2 - The efficient interaction of light and a single quantum system is required to implement a photon to spin interface. It is important to determine the amount of coherent and incoherent photons in such a scheme, since it is based on coherent scattering. In this paper an external laser field is efficiently coupled to a single nitrogen vacancy center in diamond. We detect the direct extinction signal and estimate the nitrogen vacancy's extinction cross section. The exact amount of coherent and incoherent photons is determined against the saturation parameter. This reveals the optimal point of interaction for further experiments. A theoretical model allows us to explain the deviation to an atom in free space. The introduced experimental techniques are used to determine the properties of the tight focusing in an interference experiment and allow for a direct determination of the Gouy phase in a strongly focused beam.
