Abstract
The pump-probe method of studying of the optical properties of a semiconductor in the exciton region of a spectrum is considered theoretically taking into account the exciton–photon and elastic exciton–exciton interactions. It is shown that the concentration of excitons, and the susceptibility of the medium are mainly determined by the detuning from the exciton resonance and the magnitude of the pump field. The values of the parameters corresponding to the observed parametric resonance are obtained and the dynamic analysis of the found solutions is carried out.
