Реферат: eng: This paper presents the results of modeling the most important component of a one-step technology of fabricating kinoform lenses in thick photoresist layers with increased diffraction efficiency due to the formation of backward slopes of Fresnel zones with a steepness of up to 90 degrees using oblique laser beams. It is shown that this method of fabricating volume structures makes it possible to significantly increase the steepness of backward slopes of the zones in low-contrast photoresists (k = 3) and to form practically vertical slopes in moderate-contrast photoresists (k = 10).
