We demonstrate for the first time the strong temporal hysteresis effects in the kinetics of the pumped and scattered polariton populations in a planar semiconductor microcavity under a nano-second-long pulsed resonant (by frequency and angle) excitation above the lower polariton branch. The hysteresis effects are explained in the model of multi-mode scattering when the bistability of the nonlinear pumped polariton is accompanied by the explosive growth of the scattered polaritons population. Subsequent self-organization process in the nonlinear polariton system results in a new -- dynamically self-organized -- type of optical parametric oscillator.
