Abstract: Samples of volume reflection gratings with a wide range of periods are obtained using a holographic setup with prism coupling of radiation into the recording layer of a photopolymer material. High-order reflections on these gratings are experimentally detected. The dependence of the characteristics of observed reflections on the grating parameters and recording conditions are discussed, and the experimental and calculated wavelengths of the reflections are compared.

Keywords: volume holograms, Bragg diffraction, reflection gratings, photopolymers.
