The study of direct recording of the surface relief gratings on amorphous chalcogenide thin films is presented. Direct patterning was performed on As2S3 by 532 nm wavelength laser light using a 10 The evolution of a surface relief in dependence from the recording time and polarization has been investigated in detail. It has been shown that the formation of surface relief grating closely depends on the superposition of electric field of the gradient beam and supplemental beam, thus the mass transfer can be directed both ways – towards or away from the electric field intensity gradient..
