ON THE NATURE OF THE RESONANCE FLUORESCENCE-SPECTRUM OF A DRIVEN 2-LEVEL ATOM IN AN OFF-RESONANT SQUEEZED VACUUM

We present analytical and numerical results for the steady-state reson ance fluorescence spectrum produced by a coherently driven two-level a tom in the presence of a broadband squeezed vacuum. Here the central f requency of the squeezed vacuum is off-resonant with the driving field frequency, while maintaining resonance between the driving frequency and the atomic resonance. Numerical solutions of the Bloch equations o f the system are obtained under the strong driving field approximation which agree well with the analytic results.
