The frequency spectrum of the fluorescence must be reduced when studying interactions between atoms and parametric fluorescence using the photon counting method since photon counting does not distinguish the light frequency. An interference filter and etalons successfully reduced the frequency spectrum of the parametric fluorescence from 6.6 THz to 1.7 GHz. The parametric fluorescence after frequency filtering showed the non-classical feature violating a Cauchy-Schwartz inequality for the intensity correlation function. We used slow light propagation with Rb gas to demonstrate that the obtained light source interacts with the atoms.
