Using the coupled-system approach we calculate the optical spectra of the fluorescenceand transmitted field of a two-level atom driven by a squeezed vacuum of bandwidths smaller than the natural atomic linewidth.We find that a quantum squeezed-vacuum field produces squeezing in the emitted fluorescence field which appears only in the squeezing spectrum while there is no squeezing in the total field.

The effect of squeezed vacuum input on the optical bistable behavior of a system of N three-level atoms which are simultaneously coupled to a coherent pump field and a squeezed vacuum input is investigated. It is shown that the squeezed vacuum will significantly increase the range of the optical bistability, and the bistability can be controlled by the squeezing photon number and the strength of two-photon correlation.
