“…Chalcogenide glassy semiconductors (CGS) of As-Se-S system exhibit a large implementation range, including optical information recording applications. CGS are sensitive materials to surface relief formation (mass-transport effect) under laser illumination [1][2], electron-beam recording [3][4][5], photoinduced transformation (photodarkening, photorefraction) [6][7][8], and as photoresist materials sensitive in UV-visible regions [9]. The photo-thermoplastic carriers, based on CGS [10], have high values of resolution power -up to 4000 mm -1 [11], diffraction efficiency -up to 40% [12], and 1-3 s real-time image formation [13].…”
