RECORDING OF DIFFRACTION GRATINGS WITH AN ACTIVE STABILIZATION SCHEME OF INTERFERENCE FIELD
2020
Interexpo GEO-Siberia
The paper describes a modernized optoelectronic system for stabilizing the interference pattern during exposure of a holographic grating. The results of applying the extreme control system to stabilize the interference field when recording holographic gratings of high optical quality are presented. Thin chalcogenide layers of the composition As2S3 were used as the recording medium. When using the stabilization system, a monotonic increase in the diffraction efficiency of the gratings from the
