报道了制备Ｚ－切ＫＴＰＲｂ／Ｂａ离子交换平面光波导的方法，给出了较理想的Ｒｂ和Ｂａ的ｍｏｌ％比，测量了光波导层的光损伤感度和晶格常数变化。实验结果表明：光损伤感度为１．２～２．３×１０－１０ｃｍ２／Ｊ，它与掺Ｂａ的含量和热退火工艺无关；晶格常数的变化为０．４２～０．２５％，它随着掺Ｂａ含量的增加而减少。
A method for preparing Z-cut KTPRb / Ba ion-exchanged planar optical waveguides has been reported. The ideal ratio of mol% Rb to Ba is given, and the optical damage sensitivity and the lattice constant change of the optical waveguide layer have been measured. The experimental results show that the optical damage sensitivity is 1.2 ~ 2.3 × 10-10cm2 / J, which is independent of the Ba content and thermal annealing process. The lattice constant varies from 0.42 to 0.25% With the increase of Ba content is reduced.
