提出了一种生长高质量4-(N，N-二甲氨基)-3-乙酰氨基硝基苯(DAN)单晶的方法。制备了尺寸高达10×5×2 mm~3的晶片，并对其进行了光学表征。透明区域从485 nm延伸到2270 nm。测量了大的双折射和强的折射率色散，允许产生两个I类分支和两个II类相位匹配的二次谐波。根据沿分支测量的有效二阶非线性光学极化率估算了所有的非线性极化率，最高值为D23=(50±15)pm/V。
A method of growing high quality 4‐(N,N‐dimethylamino)‐3‐acetamidonitrobenzene (DAN) single crystals is presented. Crystal plates with dimensions of up to 10×5×2 mm3 were produced and optically characterized. The transparency region extends from 485 to 2270 nm. Large birefringence and strong dispersion of the refractive indices were measured allowing two branches of type I and two of type II phase‐matched second‐harmonic generation. From effective second‐order nonlinear optical susceptibilities measured along the branches all nonlinear susceptibilities were evaluated, the highest being d23 =(50±15) pm/V.
