Spatial near-resonant effects on laser beam propagation in a multilevel photoionization system have been studied by 2D simulation. It was found that the initial amplitude of nonuniformity grows up during the propagation, which degrades the photoionization rate of the target atom. The spatial effects become large for the longer incident laser pulse. A semi-analytical formula to analyze the growth of nonuniformity in the multilevel photoionization system was derived.
