Annotation
A dynamic model of the four-photon response is proposed to interpret the dispersion relations obtained by biharmonic pumping in the range of interband absorption in gallium selenide. The intraband electron-phonon relaxation processes are described in the adiabatic approximation, with the phonon subsystem divided into the coherent active and the noise relaxation parts. The model proposed allows a qualitative description of experimental data.
