We have investigated the two-photon transition (6S1/2→6P3/2→6D5/2) of trapped atomic Cesium for excitation by squeezed vacuum generated via nondegenerate (two-color) parametric down conversion. The excitation rate exhibits a non-quadratic dependence of aI2 + bI on the incident photon flux (I), reflecting the nonclassical correlations of the squeezed vacuum field.
