Abstract The peculiarities of nonlinear transmission of ultrashort pulses of resonance laser radiation by a semiconductor thin film in the excitonic spectral region have been studied, taking into account the exciton-phonon interaction and concentration gain of the dipole moment of the excitonic transition. It has been shown that under exact resonance conditions the film transmits only the leading edge of the incident rectangular pulse and completely reflects the remaining part. For a nonzero off-resonance, a residual transmission occurs. A series of possibilities for transforming Gaussian pulses is predicted. The state equations for steady-state bistable transmission (reflection) have been derived, and the stability of the solutions has been studied. A theorem of areas, which predicts area restriction of the transmitted pulses, has been stated; namely, the transmitted pulse area cannot exceed π/2.
