摘要：

The results of surface relief and volume holographic grating (HG) formation in As(40)S(15)Se(45) films under He-Ne laser wavelength lambda = 0,6328 mu m light influence are examined. Recording beam polarisation and grating influence on surface relief parameters are shown. Microanalysis of chemical composition performed by SEM give evidence of As and Se concentration changes. Examination of beginning stage of recording kinetics demonstrates the presence of polarisation (vector) holographic gratings. Formation of complicated surface structures with different directions and dimensions are observed when hologram recording at opposite recording beam direction is carried out.
