The effect of a force of resonance light pressure on the amplitude and frequency properties of the absorption resonance dip occurring in optical saturation spectroscopy of a gas of two level atoms was studied. On the basis of numerical solutions of the Liouville and Fokker-Planck equations the behaviour pattern of the velocity distribution function of a two level atomic gas in relation to the saturation...
The prospects for application of a nonlinear laser polarization spectroscopy for measuring the steady-state population characteristics in the degenerated atomic systems with metastable lower state during optical pumping in intense laser fields are considered. It is shown that a combination of the polarization spectroscopy of a probe field and the Faraday effect allows to measure immediately the population...
