RESONANCE FLUORESCENCE OF A DRIVEN 2-LEVEL ATOM IN A CAVITY WITH INJECTED SQUEEZED VACUUM - EFFECT OF THE CAVITY FREQUENCY DETUNING

We derive, in the bad cavity limit, an effective master equation for t he reduced density matrix operator of a strongly driven atom coupled t o a frequency-tunable cavity and damped by a squeezed vacuum. We find that the intensity the resonance fluorescence spectrum and the photon- photon correlation of such an atom, emitted from the cavity, are stron gly dependent upon the cavity resonance frequency and squeezing parame ters. The enhancement and suppression of the fluorescence intensity an d spectral peaks, spectral-line narrowing, and antibunching in fluores cence call be achieved in a prescribed manner by tuning the cavity and laser frequency, and by adjusting the squeezed photon number and phas e.
