Abstract

The numerical analyses of polarization phenomena is developed for the radiation fields resonant with the transitions nS_1/2-nP_1/2,3/2 and nP_1/2,3/2 -- (n+2)S_1/2 of alkaline atoms. The method of computer simulation of nonlinear resonant polarization phenomena is used, which is based on the solution of the problem of interaction of the real multilevel atom with two laser fields of arbitrary intensity and polarization and with a constant magnetic field. This method is known to be successful applied for the investigation of the polarization phenomena in the atomic gases of the alkaline atoms Na and K. In present paper the whole alkaline group is considered. The represented spectra of rotation of plane of polarization are appear to be qualitatively different for different atoms since atom fine- structure intervals differ very much from each other. The obtained spectra for Rb are in good agreement with the experimental spectra.
