    "abstract": "We consider the interaction of a two-level atom inside an optical parametric\noscillator. In the weak driving field limit, we essentially have an atom-cavity\nsystem driven by the occasional pair of correlated photons, or weakly squeezed\nlight. We find that we may have holes, or dips, in the spectrum of the\nfluorescent and transmitted light. This occurs even in the strong-coupling\nlimit when we find holes in the vacuum-Rabi doublet. Also, spectra with a\nsub-natural linewidth may occur. These effects disappear for larger driving\nfields, unlike the spectral narrowing obtained in resonance fluorescence in a\nsqueezed vacuum; here it is important that the squeezing parameter $N$ tends to\nzero so that the system interacts with only one correlated pair of photons at a\ntime. We show that a previous explanation for spectral narrowing and spectral\nholes for incoherent scattering is not applicable in the present case, and\npropose a new explanation. We attribute these anomalous effects to quantum\ninterference in the two-photon scattering of the system.",
