Abstract
Optical recording of superimposed holographic gratings in a corona discharge initiated in a Ni-As2S3 structure is studied. It is shown that a corona discharge used for recording holographic gratings in this structure improves its holographic sensitivity and the diffraction efficiency of recorded gratings by several times. It is found that when two superimposed gratings are recorded in a corona discharge, a surface relief due to chemical etching is more uniform and the modulation depth of its thickness is larger.
