TL;DR: The unique combination of two chemical components, namely, a chain transfer agent and a free radical scavenger, is reported to enhance the holographic recording ability of a diacetone acrylamide (DA)-based photopolymer in reflection mode by 3-fold.

TL;DR: In this article, the composition and preliminary characterization of a new non-toxic photopolymer material are presented, which operates well at a range of spatial frequencies, and achieves diffraction efficiencies and refractive index modulation comparable to those of the known acrylamide-based photopolymers.

TL;DR: The aim of this paper is to discuss the benefits as well as the limitations of utilizing photopolymer materials in the design of holograms that are responsive to changes in their environment, such as changes in the concentration of a specific substance, temperature, and pressure.

TL;DR: In this article, the authors explored the humidity and temperature response of volume phase slanted gratings recorded in photopolymers with varied chemical composition and showed that the response of photopolymer-based holographic gratings to relative humidity (RH) and temperature (T) can be tuned by alteration of the photpolymer composition.

TL;DR: Results show that the incorporation of Glycerol results in a uniform maximum refractive-index modulation for recording intensities in the range of 1-20 mW/cm(2), which may be attributed to glycerol's nature as a plasticizer, which allows for faster diffusion of an unreacted monomer within the grating during holographic recording.
