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