Abstract
The weak probe field spectrum of a three-level atom, in the ladder configuration, is obtained. The lower transition of atom is coupled with squeezed vacuum, while the upper transition is coupled to coherent cavity mode and a bath. In this paper, the effect of the various quantities (detuning, decay rates) on the absorption spectrum is investigated.
