Abstract

The possibility of obtaining diffractive optics of a high diffraction order in the form of linear and circular elements in layers of chalcogenide glassy materials is shown. The conditions for obtaining layers by means of automated thermal deposition of them in high vacuum have been improved, which made it possible to double the amplitude of photostructural changes in the refractive index. The maximum diffraction efficiency of the second order of diffraction for linear gratings is obtained. The prospect of manufacturing zone plates with a maximum efficiency of up to 30 orders of magnitude of diffraction is shown.
