The dissertation is based on direct recording phenomenon, which objective is to do a research on the amorphous chalcogenide susceptibility to light. As one of the research methods, a direct holographic record will be used, i.e., creating surface relief in chalcogenides directly without any additional processing, like etching. Complete development of this method opens wide range of usage possibilities in optical element production and utilization, as well as in introduction of new and innovative technologies. There is still a lot of interesting phenomena in amorphous chalcogenide that are not well understood and explained in a microscopic level and so this work will be directly involved in the process of research. Record efficiency dependence from its parameters (intensity, polarization) and recording conditions will be examined. Optical properties for obtained nanostructures will be studied, such as transmission, reflection, diffraction efficiency, etc. The obtained structures will be viewed by atomic force microscopy, determining their shape and size.
