Abstract

Optical parameters of good quality amorphous Si-, Ge-, Se- and chalcogenide glass multilayers (ML) with 3-12 nm modulation lengths, produced by magnetron sputtering and thermal evaporation, can be significantly changed by 0.1-100 W/cm2 continuous laser irradiation. It is shown, that besides the usual photo-stimulated structural changes obtained in single chalcogenide amorphous films, in these multilayers the structural transformations are connected with interdiffusion processes and they lead to the formation of an enhanced surface relief.
