Paper Abstract

The peculiarities of the light transmission nonlinear charge were studied in the case of interband excitation of the chalcogenide glass thin films by nanosecond and picosecond light pulses. The transmission optical hysteresis due to photoinduced absorption is registered. The nonlinear behavior of the thin chalcogenide plates acting as a Fabry-Perot cavity is investigated in picosecond time scale. The possible explanation of the revealed nonlinearities is proposed.
