The broadband parametric fluorescence pulse (probe light) with center frequency resonant on the {sup 87}Rb D{sub 1} line was injected into a cold atomic ensemble with coherent light (control light). Due to the low gain in the parametric down conversion process, the probe light was in a highly bunched photon-pair state. By switching off the control light, the probe light within the electromagnetically induced transparency window was mapped on the atoms. When the control light was switched on, the probe light was retrieved and frequency-filtered storage was confirmed from the superbunching effect and an increase of the coherence time of the retrieved light.
