We present study of the parameters of polarization holographic gratings recorded in thin films of the azopolymer PAZO (Poly[1-[4-(3-carboxy-4-hydroxyphenylazo) benzenesulfonamido]-1,2-ethanediyl, sodium salt]) and in a composite PAZO-based organic/inorganic material with incorporated TiO₂ nanoparticles with size 21 nm and different concentrations. The gratings are inscribed by two plane waves with left and right circular polarization from a He-Cd gas laser (442 nm) at recording angle 20°. Along with the anisotropic grating in the volume of the media, surface relief is also formed. Gratings with different spatial frequencies are obtained by varying the recording angle. The diffraction efficiency kinetics is probed at 635 nm and the height of the relief gratings is determined by AFM. Our results indicate that the diffraction efficiency for the hybrid samples is enhanced with respect to the pure azopolymer films. Comparison is also made between polarization response of samples deposited from water and from methanol solution.

我们目前对偶氮聚合物PAZO（聚[1- [4-（3-羧基-4-羟基苯基偶氮）苯磺酰胺基] -1，2-乙二胺，钠盐]）薄膜中记录的偏振全息光栅参数的研究掺有TiO ₂的复合PAZO基有机/无机材料具有21 nm大小和不同浓度的纳米粒子。光栅被来自He-Cd气体激光器（442 nm）的左右圆偏振的两个平面波以记录角20°内切。与介质体积中的各向异性光栅一起，还形成了表面浮雕。通过改变记录角度可以获得具有不同空间频率的光栅。在635 nm处探测衍射效率动力学，并通过AFM确定浮雕光栅的高度。我们的结果表明，相对于纯偶氮聚合物薄膜，杂化样品的衍射效率得到了提高。还比较了从水和甲醇溶液中沉积的样品的极化响应。
