非线性光学（NLO）材料随着大量利用固态激光源的设备的出现而获得了新的意义。从这一技术观点来看，具有上级的非线性光学性质的磷酸二氢钾（KDP）已被开发用于各种应用。为了获得较好的非线性特性，采用缓冷法从水溶液中添加有机添加剂生长KDP晶体。研究了有机添加剂对薄膜光学性能和力学性能的影响。已经观察到，有机添加剂的加入提高了晶体的机械强度。还观察到，有机添加剂的添加提高了晶体的光透射百分比。
Non-linear optical (NLO) materials have acquired new significance with the advent of a large number of devices utilising solid-state laser sources. From this technological point of view, potassium dihydrogen phosphate (KDP) having superior non-linear optical properties has been exploited for variety of applications. KDP crystals were grown from aqueous solutions added with organic additives by the slow cooling method for obtaining better non-linear properties. The influence of the organic additives on the optical and mechanical properties has been studied. It has been observed that the addition of organic additives improves the mechanical strength of the crystal. It is also observed that the addition of organic additives improves the optical transmission percentage of the crystal.
