The relationships governing nonlinear transient transmission and reflection of ultrashort resonant laser radiation pulses with rectangular and Gaussian profiles by a thin semiconductor film were investigated taking into account the exciton-photon interaction and the concentration enhancement of the dipole moment of the exciton transition. It is shown that the transmission of a Gaussian pulse is characterised by the formation of two subpulses with identical areas, which are separated in time and have different profiles.
