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.

Collective resonance fluorescence in a squeezed vacuum

Tran Quang, M. Kozierowski, L. H. Lan

The resonance fluorescence of a small sample of N two-level atoms driven by a strong resonant coherent field and damped by a squeezed vacuum is examined. The steady-state spectrum is shown to be dramatically dependent on the relative phase of the pumping field and on the squeezed-vacuum field in both the strong- and weak-squeezing limits.
