Abstract. We report results of a theoretical and experimental study of the ground state nonlinear Hanle
effect under strong laser excitation. It is shown that besides the well-known zero-magnetic field suppression
of absorption on Fg = F - Fe = F - 1 transitions caused by population trapping, an optical pumping
induced enhanced absorption occurs on Fg = F - Fe = F + 1 transitions for small B-fields. The latter
effect becomes more pronounced for high F values. The experiment with atomic vapor of Cs (D2 line,
