Supershort pulse splitting under resonant reflection from a thin film

The nonlinear dynamic effect — splitting of the supershort optical pulse reflected by a dense resonant medium thin layer is simulated. The effect arises as a result of the coherent interaction, developing in a dynamic phase adjustment of the laser pulse field and the polarization of the medium of a thin layer. The decisive factor in the development of the splitting process is the effect of the phase shift due to the influence of neighbor dipole interactions on the absorption line.
