Influence of Softening Temperature of Azobenzene Polymers and External Electric Field on Diffraction Efficiency of Polarization Holograms

Abstract

Growth of the diffraction efficiency and recording velocity was found in the films of copolymers 4-((2- nitrophenyl) diazeniyl)phenylmethacrylate) with octylmethacrylate at room temperature holographic recording for copolymer with less softening temperature. Effect of strengthening of the diffraction efficiency was observed when charging surface of the films with recorded hologram in crown discharge.
