Fluorescence Spectrum from a Three-Level Atom Interacting with a Monochromatic and Broadband Laser

Abstract

The fluorescence spectrum emitted from a three-level atom interacting with two strong resonant fields has received considerable attention. The three-level atom in the ladder-type configuration has been studied by Whitley and Stroud and others.^{1, 2} However, the V-type configuration (see insert figure 1) has received much less attention. Using a method similar to Whitley and Stroud a computer generated spectrum is calculated both on and near resonance. The resulting spectrum appears to be in some disagreement with the literature.³ However, our results can be understood on a physical basis by employing rate equation techniques and by an approximate calculation of the eigenvalues of the Hamiltonian.
