    "abstract": "We propose an implementation of the parametric amplification of an arbitrary\nradiation-field state previously prepared in a high-Q cavity. This nonlinear\nprocess is accomplished through the dispersive interactions of a single\nthree-level atom (fundamental |g\u003e, intermediate |i\u003e, and excited |e\u003e levels)\nsimultaneously with i) a classical driving field and ii) a previously prepared\ncavity mode whose state we wish to squeeze. We show that, in the adiabatic\napproximantion, the preparation of the initial atomic state in the intermediate\nlevel |i\u003e becomes crucial for obtaing the degenerated parametric amplification\nprocess.",
