Nonclassical excitation for atoms in a squeezed vacuum

Creators

Abstract

The two-photon transition 6S(1/2) --> 6D(5/2) is investigated for trapped atomic cesium excited by squeezed light. The rate R of two-photon excitation versus intensity I is observed to be consistent with the functional form R = beta(1)I + beta(2)I(2), extending into a region with slope 1.3. This departure from the quadratic form for classical light sources is due to the fundamental alteration of atomic radiative processes by the nonclassical field.
