Induced dichroism in molecular gases was studied using a three-level scheme. A density-matrix calculation in all orders of the pump field that are linear in the probe field may lead to a coherent dip in the absorption-line shape of the probe field, depending on the polarization arrangement. Such a coherent dip is a manifestation of the polarization pulsation induced by the fields.
