| 摘 要： | 合成了一种新的含偶氮基的三元共聚物，由于在主链中链接柔性基团，使其具有相对较低的玻璃化温度，在６３３ｎｍ处光感生双折射δｎ值可达１０＾－３量级。实验上获得了几个乃至几百微米厚的具有高光学无效性的薄膜，在６３３ｎｍ波长处写一息光栅的实时单光束衍射效率可达１０％以上。

| Abstract: | A new azopolymer material has been developed. Real time holograms were recorded at 633 nm, and read out by beam with the same wavelength. High diffraction efficiency above 10% was obtained, and large photo induced birefringence δ n>10 -3 was measured. |

| Keywords: | azopolymer holography grating photoinduced birefrignence |
