Abstract
The dependence of holographic recording on recording light intensity has been experimentally studied in nonannealed amorphous As2S3 films. It has been observed that the threshold of the recording intensity is about 10−5 W/cm2 for 10.5‐μm‐thick film and a 1 μm grating period. A phenomenological model is presented to explain the intensity dependence in the 10−5–10−1 W/cm2 intensity range. According to this model the observed intensity behavior is caused by photoinduced spatially periodic mechanical stress.This publication has 7 references indexed in Scilit:
