Abstract: A new variant of manufacturing high–frequency holographic gratings with a spatial frequency up to 1500 mm$^{-1}$ on layers of dichromated gelatin (DCG), in the processing technology of which water procedures are completely excluded, is proposed. The method is based on the use of glacial acetic acid instead of the standard method of processing holographic structures registered by coherent He–Cd laser radiation after the destruction of layers by exposure to short-wave UV radiation. In the course of the experiments, relief-phase holographic gratings with high diffraction efficiency up to 64
