Abstract
It is shown that the linear recording of holographic gratings can be obtained at 514 nm in the amorphous arsenic trisulfide films. While strong nonlinearity was observed during recording at room temperature, these effects were eliminated when the recording was performed at temperatures below 275 K. To verify the linearity of the recording, the first- and second-order diffraction of a recorded grating were monitored during exposure. Since temperature appeared to be an important factor in obtaining the linearity of the recording, the experimental results support our qualitative model in which photoinduced structural changes, the main recording process, are deteriorated by a competitive relaxation process.
