Abstract

We investigated ultrafast nonlinear optical properties of periodic structures based on ZnSe/ZnS using interband and two-photon excitation of ZnSe sublatice by nano-, pico-, and femtosecond laser pulses. A considerable shift of reflection spectrum and large relative reflection changes were observed in a wide spectral range corresponding to the transparency region of ZnSe far from the intrinsic absorption onset. The nonlinear refraction is supposed to be controlled by population induced absorption changes in ZnSe and the relaxation time is controlled by a transition from non-equilibrium to quasi-equilibrium distribution of electrons and holes.
