Abstract
The amorphous As<sub>2</sub>S<sub>3</sub> and As<sub>40</sub>S<sub>15</sub>Se<sub>45</sub> films as a recording media for optical holography and lithography were studied. The results on research of the transmission, surface-relief and Bragg reflection grating holographic recording and readout conditions are presented. The recording of transmission holographic gratings in As<sub>40</sub>S<sub>15</sub>Se<sub>45</sub> films was performed by He-Ne (0.6328 μm) laser beam, while the redout of the diffraction efficiency was made at Bragg agle using diode (0.805 μm) laser lines. The Bragg reflection gratings in As<sub>2</sub>S<sub>3</sub> films were recorded and studied by Ar<sup>+</sup> laser line 0.5145 μm. The surface-relief modulated gratings with a period of 0.15 μm - 1 μm were recorded.
