Abstract:In this report an all-optical photo-induced formation of surface relief gratings is shown. For the surface patterning of As2S3and As4S1.5Se4.5films a direct holographic recording setup with a 532 nm wavelengthNd:YAGCW laser light was used. Our investigations have shown that the light-induced mass transfer process strongly depends on the material itself and on the polarization of the light. It has been shown that an electric field intensity gradient has to be obtained to achieve a direct patterning. The evoluti… Show more
