Abstract

Maxwell-Bloch equations generalized for a dense medium of two- level atoms are used to describe the dynamics of the system under the action of an ultrafast optical pulse. Starting with an uninverted system, the final population is one of the two extreme cases, depending on the ratio of the Rabi frequency and the parameter describing the near dipole-dipole interactions. Based on numerical investigations for typical pulse shapes, the mechanism of switching is explained.
