We have carried out two-beam interference experiments to form holographic gratings on As$_{40}$ Se$_{15}$ S$_{35}$Ge$_{10}$ single layer, Ag/As$_{40}$ Se$_{15}$ S$_{35}$Ge$_{10}$ multi-layer In this study, holographic gratings have been formed using He-Ne laser(632.8nm) under different polarization combinations(intensity polarization holography, phase polarization holography). The diffraction efficiency was obtained by the +lst order intensity The maximum diffraction efficiency of As$_{40}$ Se$_{15}$ S$_{35}$Ge$_{10}$ single layer, As$_{40}$ Se$_{15}$ S$_{35}$Ge$_{10}$ and MgF$_2$/As$_{40}$ Se$_{15}$ S$_{35}$Ge$_{10}$ multi-layer were 0.8%, 1.4% and 3.1% under intensity polarization holography, respectivelygraphy, respectivelyspectively
