“…Most of the gratings used are phase gratings manufactured either by cutting using a ruling machine [1,2] or by lithographical methods [5]. Thermochemical chrome oxidation remains the most developed and common method of producing lithographic masks and diffraction optical elements (DOEs) both for binary [6,7] and gray-scale DOEs [8]. Comparatively recently research has been underway devoted to further development of the technology of the additive method of producing phase grating microrelief [9,10].…”

“…about 0.8 μm [10]. In this regard, the actual task is the development of technological methods for creating elements with high spatial resolution.On the basis of the above-described process sequence, for example, in [11], there has been an element size of 0.5 μm on the structure of the chromium films 50 nm thick inflicted thermal vacuum process substrates of optical glass.Patent [12] describes how to increase the resolution of the method of laser thermochemical oxidation film of titanium thickness of 3 -60 nm, deposited on the glass substrate.A characteristic feature of the studies described in [1][2][3][4][5][6][7][8][9][10][11], is that the resistance to the subsequent chemical resistance increases for portions of film exposed to the laser radiation. In contrast to [1][2][3][4][5][6][7][8][9][10][11], we propose an approach based on evaporation (ablation) portions of the film exposed to laser radiation.…”
