Calculation of cross sections for resonance Raman scattering by atoms in strong radiation fields and a magnetic field

The method of computer simulations on nonlinear resonant magnetooptical effects developed for the first time for real multilevel atoms in the two laser fields of arbitrary intensity and external magnetic field is applied for Raman-effect cross section calculations and investigations of the dependence on magnetic field strength, intensities, detunings of laser fields for alkaline atoms, thallium. Calculations of nonlinear resonant Raman-effect cross- sections in the intense laser fields resonant to adjacent transitions and magnetic field show the opportunity of appearing of the new effects in Raman scattering in atomic gases.

For the model of a plane rotator in an intense circularly polarised wave the response of the quantum system to the intense field and a weak monochromatic perturbation is obtained. The authors calculate the cross sections for coherent and Raman scattering of the strong field and cross sections for elastic and inelastic scattering and absorption and emission of the weak field.

An inhomogeneous differential equation method is used to calculate the Rayleigh and Raman scattering cross sections for atomic hydrogen and atomic caesium as functions of wavelengths below and above the ionization limits. The profile of the scattering cross section near the 6s-6p resonance of atomic caesium is determined by including an energy-independent radiative width in the scattering formula. The effect of replacing the electric dipole operation by a modified form that takes account of the polarization of the core by the valence electron is explored.
