The studies of direct holographic recording of the surface relief gratings (SRG) on amorphous As40S60-xSex (0≤x≤60) thin films are presented. The gratings were created by orthogonally ±45° linearly polarized light beams of various wavelengths (λ = 473 - 650 nm). The surface structure of the relief gratings was investigated by atomic force microscopy. The influence of laser beam wavelength and spatial frequency of the gratings (grating period Λ) on the surface relief grating formation efficiency was examined..
