集中的 holographic 在一张唑相片光完成没有使用一个偏爱领域,在 632.8 nm 波长的折射电影被观察,由于在材料的二横梁的联合过程。材料从 3-formyl-N-vinylcarbazole (99 wt%) 和 2,4,7-trinitro-9-fluorenone (1 wt%) 的混合被准备。
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%).
