The time evolution of an intense polariton wave has been studied in the framework of a microscopic approach. It has been shown that due to polariton–polariton scattering a significant polariton wave depletion takes place in a comparatively short time interval. The condensate decay occurs in the form of multiple echo signals. Distribution‐function dynamics of scattered polaritons have been investigated.
