The authors discuss the problem of collective resonance fluorescence of N driven atoms which are damped by a white squeezed noise. Analytical formulae for the spectrum of resonance fluorescence and for the degree of second-order coherence for spectral lines are calculated. The narrowing or expansion of linewidths and the asymmetry of the spectrum caused by the squeezed vacuum are shown.

Fluorescence from a coherently driven two-level atom that is damped by a squeezed vacuum is studied. We show that the mean atomic polarization depends on the relative phases of the squeezed vacuum and the coherent driving field. The fluorescent spectrum is calculated and shows several modifications over the spectrum for normal resonance fluorescence. In particular, the central peak of the Mollow triplet has a linewidth that depends on the phase of the driving field. For strong squeezing this peak can either be much narrower or much broader than the natural linewidth of the atom.
