Abstract

The subject of atomic spectroscopy with squeezed light has received a great deal of attention in recent years. The review article by Parkins¹ summarizes much of this work. However, most of the predictions have been derived under the assumption that the bandwidth of squeezed vacuum field is broad relative to the natural atomic linewidth and the Rabi frequency of a driving field. Moreover, it has been assumed that an atomic system interacts exclusively with squeezed modes of the radiation field. Present sources of squeezed light generate squeezed beams that can cover only a relatively small solid angle of the modes coupled to the atomic system and that have bandwidths only of the order of typical atomic linewidths.² Therefore, the coupling to unsqueezed modes and a finite-bandwidth effects should be incorporated into the theory of the interaction between atomic systems and squeezed fields.
