    "abstract": "By means of quantum stochastic calculus we construct a model for an atom with\ntwo degenerate levels and stimulated by a laser and we compute its fluorescence\nspectrum; let us stress that, once the model for the unitary atom-field\ndynamics has been given, then the spectrum is computed without further\napproximations. If only the absorption/emission term is included in the\ninteraction, we reobtain the Mollow spectrum in the case of a monochromatic\nlaser and the Kimble-Mandel spectrum in the case of a \"phase diffusion model\"\nfor a non monochromatic laser. However, our model can describe also another\ntype of light scattering, a \"direct scattering\" due to the response of the atom\nas a whole, which we expect to be small, but which interferes with the\nscattering due to the absorption/emission channel. When both the scattering\nchannels are introduced we obtain a modification of the Mollow-Kimble-Mandel\nspectrum, which shares the main features with the usual case, but which\npresents some asymmetries even in the case of no detuning.",
