用相干激光在4-二甲氨基偶氮苯单晶的（100）面上形成表面起伏光栅（SRG）。SRG的形成取决于晶体的取向和写入光的偏振方向。结果表明，光诱导SRG的形成是通过从亮区向暗区的质量输运发生的。此外，发现存在于所得SRG的凸区域中的分子根据下面的晶体取向。
Surface relief grating (SRG) can be fabricated on a (100) surface of a single crystal of 4-(dimethylamino)azobenzene by irradiation with coherent laser beams. The SRG formation depended upon both orientation of the crystal and polarization direction of the writing beams. It was suggested that the photoinduced SRG formation took place by mass transport from the bright region toward the dark region near the surface of the crystal. In addition, the molecules existing in the convex region of the resulting SRG were found to be oriented according to the underlying crystal.
