Abstract
Infrared imaging materials with high speed and dynamic range are required f or a variety of imaging and diagnostic techniques. We present an organic ph otorefractive glass that shows high diffraction efficiencies of as great as 40% with 25-mu m-thick samples and fast response times of 4.3 ms under irr adiation at 790 nm. Furthermore, the intensity dependence and field depende nce of the grating decay are investigated. (C) 2000 Optical Society of Amer ica. OCIS codes: 090.2900, 160.5320.
