TIME KINETICS OF POLARITON LUMINESCENCE OF SEMICONDUCTOR CRYSTALS UNDER RESONANT EXCITATION OF EXCITONS

A theory of the time kinetics of resonant polariton luminescence under pulsed exciton excitation for cubic crystals is developed taking into account spatial dispersion, inhomogeneity of the distribution function in space, polarization state, and multiple processes of elastic scattering of polaritons. With the help of the Laplace transform, the Ŝ - matrix method is developed for solving the time-dependent matrix integro-differential transport equation in the case of a strong light-exciton interaction
