1 RCMO - RCMO

Recording of binary volumetric diffractive optical elements within a 13 μm thick photosensitive chalcogenide layer using an innovative exposure setup based on digital micromirror devices is demonstrated. Different examples of beam transformations, such as the conversion of a Gaussian beam into higher-order modes or top-hat beam shapers, are shown.
