Study of the optical properties of a molecular system interacting with a high-intensity electromagnetic field

It was studied the solvent influence over a two level system interacting with an electromagnetic field using an stochastic treatment. It was considered a high-intensity electromagnetic field which is capable to produce local saturations. The induced coherence in the two electronic states, was averaged in the usual form, through both, lorentzian and gaussian probability density. From that, analytical expressions for susceptibility and optical properties were obtained. Numerical calculations were carried out to construct surfaces corresponding to this properties as a function of the field variables and the distributions parameters.
