Abstract

In the present work the photoinduced phenomena in chalcogenide glasses thin films, that have direct relation to the optcial record, storage and its copying was considered. The main properties of selected chalcogenide photoresist films are presented. The parameters of photoresistive layers for two regimes of laser irradiation (continuous and pulse) are given. The reflective diffraction gratings with high efficiency were obtained in the result of holographic recording, subsequent chemical treatment, and metallization of the photoresist surface. A considerable increase in the light sensitivity was achieved due to the optimization of the photoresist composition, the recording and etching conditions. The possibilities of additional increase of photoresist sensitivity are discussed.
