Photorefractive Properties of Bisphenol-A-4,4'-Nitroaminostilbene Mixed with Diethylaminobenzaldehyde-Diphenyl Hydrazone

Abstract

We report the photorefractive properties of a new polymer mixture composed of 40 wt. % benzaldehyde-diphenyl hydrazone dissolved in Bisphenol A 4,4'-nitroaminostilbene. The polymer has a response time of 0.11±0.02 sec at 1 W/cm2, an overall photorefractive sensitivity (index change per unit absorbed energy density) of 1.8±0.5 × 10−6 cm3/J.
