Abstract

We investigate a coupled atom-cavity system in which a two-level atom is driven by a classical field. It is shown that the cavity mode, which is in a coherent state in the absence of its reservoir, can be squeezed via coupling to the reservoir. The squeezing effect is enhanced to some extent as the cavity damping rate is increased. In particular, we obtain an unusual optimal condition for the squeezing in which the pumping field is inversely proportional to the damping rate.
