A new PVK-based photorefractive polymer composite sensitized by C₆₀ and doped with a higher content of EO chromophore was prepared.The high optical quality thin-film was formed between two ITO-covered glass electrodes.Two-beam-coupling (2BC) experiment was performed by using a He-Ne laser (at wavelength 632.8nm),and an obvious photorefractive performance was observed.The dependence of two-beam-coupling gain coefficient on the applied poling dc electric field was measured.
