dcterms:description
Photorefractive materials are recording media that can be used for holographic recording. In our contribution, an experimental study of the photorefractive effect in poly(N-vinyl carbazole) (PVK) with N-ethylcarbazole (ECZ) doped with new nonlinear optical chromophores 4-Nitro-2'-acetylamino-4'-(N,N-dimethylamino)azobenzene or 4-Cyano-4'-(N,N-diethylamino)azobenzene is presented. These two chromophores are sensitive enough to the wavelength 532 nm, so no sensitizers are needed. Using the materials, we have demonstrated four-wave mixing experiments with visible laser beams at a room temperature with using a high voltage power supply and without. The writing laser beam had the wavelength 532 nm and the reading laser beam 658 nm. Photorefractive materials are recording media that can be used for holographic recording.
