Monochrome and Two-Color Holograms in Layered Photopolymer Materials

The layered systems of holographic photopolymer materials for recording color holograms are designed and developed. Monochrome and two-color (green-red, red-blue, and green-blue) volume reflection holograms are obtained using the He—Ne, Ar+, and DPSS lasers in red, green, and blue spectral ranges. The effects of cross-bleaching of the dyes used and the holographic properties of monochrome and two-color holograms in layered systems are considered. It is shown experimentally that the diffraction efficiency of these holograms is ~(70–80%) and comparable with that of monochrome holograms obtained in single-layer holographic photopolymer materials.
