Photorefractive polymer composite with net gain and subsecond response at 633 nm

By combining the well-known photoconductor poly(N-vinyl carbazole) sensitized with 2,4,7 trinitro-9-fluorenone and the electrooptic molecule N,N,diethyl-substituted para-nitroaniline, which is transparent at 633 nm, a photorefractive polymer composite suitable for applications with He-Ne lasers was developed. Net gain of 18 cm-1 and 400 ms response time were measured on a 65-mum-thick sample.
