摘　　要：The holographic focusing effects of light in a carbazole photorefractive film at 632.8 nm wavelength were observed without applying a bias field, owing to the two-beam coupling process in the material. The material was prepared from the mixture of 3-formyl-N-vinylcarbazole (99 wt%) and 2,4,7-trinitro- 9-fluorenone (1 wt%).The holographic focusing effects of light in a carbazole photorefractive film at 632.8 nm wavelength were observed without applying a bias field, owing to the two-beam coupling process in the material.
