Some characteristics of semiconductor-metal light-sensitive systems and holographic diffraction gratings based on them

The results are given of an investigation of some characteristics (spectral distribution of the sensitivity, dependences of the diffraction efficiency on the exposure and spatial frequency) of light-sensitive semiconductor-metal systems composed of Ag, As, S, and Se. A description is given of some properties of holographic diffraction gratings based on these systems deposited on plane and spherical substrates. It is shown that semiconductor-metal systems of this kind can be made into diffraction gratings characterized by a high resolution, small aberrations, and weak scattering of light.
