ANOMALOUS RESONANCE FLUORESCENCE FROM AN ATOM IN A CAVITY WITH INJECTED SQUEEZED VACUUM

As a realistic system for observing the distinctive features of the in teraction of squeezed light with atoms, we consider a single, coherent ly driven, two-level atom in a resonant optical cavity coupled to a br oadband squeezed vacuum field. In the bad cavity limit we derive equat ions of motion for the atomic operators that are identical to those fo r the free-space situation, except for having modified parameters. We focus our attention on the resonance fluorescence from this system and show that, in the above limit, many of the unusual spectral features previously reported for the free atom situation persist. We also confi rm the link between these anomalous spectra and the collapse of an ato m into a pure state. The cavity parameter values needed to verify some of these interesting effects appear to be within the range of present day technology.
