Extinction of Light and Coherent Scattering by a Single Nitrogen-Vacancy Center in Diamond | | Thai Hien Tran

18 Aug 2016 | | Abstract: | Coherently scattered light from a single quantum system promises to get a
valuable quantum resource. In this letter an external laser field is
efficiently coupled to a single nitrogen vacancy (NV-)center in diamond. By
this it is possible to detect a direct extinction signal and estimate the NV’s
extinction cross-section. The exact amount of coherent and incoherent photons
is determined against the saturation parameter, and reveals the optimal point
of generating coherently scattered photons and an optimal point of excitation.
A theoretical model of spectral diffusion allows 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. | | Source: | arXiv, 1608.5224 | | Services: | Forum | Review | PDF | Favorites | |
