Investigation on the panchromaticity of silver-doped poly(vinyl alcohol)/acrylamide photopolymer
TLDR
It was noted that transmission gratings with 70% diffraction efficiency could be recorded using Ar⁺ and Nd:YAG lasers, thereby elucidating the possibility of using the developed photopolymer system as a competent panchromatic recording medium.Abstract:
An investigation on the panchromaticity of a silver-doped poly(vinyl alcohol)/acrylamide photopolymer system is presented in this paper. Frequency-doubled Nd:YAG (532 nm) and Ar⁺ (488 nm) lasers were used for the characterization of the films. Previous studies using an He-Ne laser (632.8 nm) showed that plane-wave transmission grating with a high diffraction efficiency of 75% could be stored in the optimized film. From the present study, it was noted that transmission gratings with 70% diffraction efficiency could be recorded using Ar⁺ and Nd:YAG lasers, thereby elucidating the possibility of using the developed photopolymer system as a competent panchromatic recording medium.read more

Research on Holographic Sensors and Novel Photopolymers at the Centre for Industrial and Engineering Optics
TL;DR: The photopolymer materials consist of a light-sensitive film which is exposed during production to form the hologram, thereby offering versatility well beyond that of current security holograms, which are mass produced from a master using a foil stamping processes.

Stretching the sensitivity and stability of an acrylamide based photopolymer material with mixture of dyes
TL;DR: In this paper, the authors investigated the possibility of extending the limited absorption range towards the entire visible range by simple modifications in the photopolymer composition so that panchromaticity can be invoked in the material.

Photopolymerizable Nanocomposites for Holographic Recording and Sensor Application
TL;DR: It was found that the zeolite Beta nanoparticles behave as a noninert additive, resulting in an effective increase in layer thickness, which causes doubling of the diffraction efficiency of the nanocomposite in comparison to the undoped photopolymer.

Two-way diffusion model for short-exposure holographic grating formation in acrylamide-based photopolymer
TL;DR: In this paper, a theoretical model for the formation of a short-exposure holographic grating is presented, which accounts for both monomer and polymer diffusion and distinguishes between short polymer chains capable of diffusing and long polymer chains that are immobile.
