Abstract

An optical hysteresis and nonlinear absorption of the microsecond and nanosecond laser pulse at interband excitation of different a-Si:H and a-SiC:H films are reported. To explain the experimental results a new physical model is suggested, taking into account the light interaction with nonequilibrium localized lattice vibrations anharmonically coupled with the extended phonons
