“…The fitting procedure was implemented by means of the Origin program for the gratings with four different periods (from 1.8 to 9.8 μm) recorded under the same conditions. The dependence of γ on the value d −2 was found to be linear (figure 2, inset) as it should be under diffusion enhancement, according to equation (4). These findings allow one to assume that the diffusion plays the main role for the hologram enhancement for NQ-containing materials.…”

“…One of the classical materials for use in phase holography with post-exposure enhancement is a polymer matrix (often polymethylmethacrylate (PMMA)) containing phenanthrenequinone (PQ) [1][2][3][4][5][6][7][8][9]. This material has been known of since the 1990s, and over the years several formulations (including using polymerization in the bulk [1] or casting with subsequent drying [7,8]) and a number of applications have been realized.…”

A new material based on 1,2-naphthoquinone in polymethylmethacrylate is proposed for phase holograms showing diffusion enhancement. The spectral sensitivity of this material allows forming holograms using 488–530 nm wavelengths, while the hologram reconstruction can be implemented at 633 nm. The amplitude of the refractive index modulation achieved makes it possible to reach diffraction efficiencies close to 100% at a thickness of several hundreds of µm. It was found by means of UV–visible and NMR spectroscopy that the diffusion of 1,2-naphthoquinone caused by photoproduct attachment to macromolecules of a polymer matrix is the main reason for the hologram enhancement. A relatively high diffusion coefficient (4.8 × 10−17 m2 s−1 at 50 °C) was measured, leading to fast enhancement at moderate temperature.

PQ/PMMA photopolymer films fabricated by solvent casting are realized using tetrahydrofuran (THF) as the solvent. The corresponding photochemical reaction model is established with material parameters numerically studied based on 57 samples recorded with a 532 nm laser. The fabrication and the recording time are noticeably reduced. A 2-fold increase in the average refractive index variation is achieved compared with the two-step thermal polymerization method with the same PQ initial concentration.

“…Phenanthrenequinone-doped poly(methyl methacrylate) (PQ/PMMA) photopolymers are suitable for polarization holography due to its photoinduced birefringence [7]. In addition, PQ/PMMA photopolymer has good optical quality and negligible photoinduced shrinkage [8,9]. Photo-induced birefringence in PQ/PMMA film was first observed in 1999 [10].…”

We present an experimental study on the optical polarization properties of the phenanthrenequinonedoped poly(methyl methacrylate) photopolymer materials. We discuss the diffraction efficiency with different weight ratios of phenanthrenequinone that was dissolved in the materials. In addition, we observe the diffraction efficiency difference between polarization holography and traditional holography.
