Abstract

Infrared imaging materials with high speed and dynamic range are required for a variety of imaging and diagnostic techniques. We present an organic photorefractive glass that shows high diffraction efficiencies of as great as 40% with 25-µm-thick samples and fast response times of 4.3 ms under irradiation at 790 nm. Furthermore, the intensity dependence and field dependence of the grating decay are investigated.
