Abstract
The possibility of application of nonlinear laser polarization spectroscopy for measuring the steady-state population characteristics in degenerated atomic systems with metastable lower state during optical pumping in intense laser fields is considered. It is shown that a combination of polarization spectroscopy of probe field and the Faraday effect allows to measure directly the population differences for "enriched " and "depleted" Zeeman's sub-levels during the process of optical pumping as well as for optically coupled sub-levels of lower and upper states of the transition. The experimental results for the transitions 1s5?2p2 (J=2?J=1) and 1s5?2p4 (J=2?J=2) Ne20 and their comparison are presented.
