Dynamic laser-induced gratings (LIG) are investigated in CdS and ZnO. The microscopic processes resulting in the formation of LIG are discussed. A nonlinear coupling is found between oscillators active in the polarizations{E} ⊥ {c}and{E} ∥ {c}, respectively. The influence of induced absorption optical bistability on the temporal evolution of LIG is observed and qualitatively discussed.
