Abstract: Based on the numerical solution of the system of Maxwell–Bloch equations, a comparison is made of the dynamics of the population difference gratings and the polarization of the medium, modeled in the two- and three-level approximation. It is shown that gratings also appear in a three-level medium, but their dynamics are not qualitatively different from a two-level medium with the selected model parameters.
Keywords: population difference gratings, half-cycle pulses, attosecond pulses, coherent effects, two-level medium.
