Abstract
This letter reports preliminary results of experiments involving the storage of high‐efficiency holograms in evaporated thin films of arsenic trisulfide (As2S3). Both simple gratings and holograms of complex data masks have been recorded in the films by direct exposure with no subsequent processing. Diffraction efficiencies of up to 80% have been measured for two‐beam gratings. Several possible mechanisms are suggested to explain the observed results.Keywords
