Abstract

The results of experiments on the effect of ultraviolet (UV) radiation with a wavelength of less than 250–270 nm on holographic structures recorded on dichromated gelatin (DCG) layers are presented. A tenfold increase in the height of the surface relief and an increase in the diffraction efficiency of the gratings to approximately 30% over a wide range of thicknesses of DCG layers—1 to 80 μm—are obtained. The experiments show that the main cause of the formation of the surface relief is the variable tanning of the layer, which occurs when the interference pattern is recorded with coherent radiation at a wavelength of 0.44 μm and serves as a factor that modulates the impact of UV radiation.
