本文研究了掺氧化镁锂（MgLN）的极化特性和周期极化。利用电场法进行周期性极化，制作出均匀的光栅。测量了作为极化场函数的畴壁速度，并用于确定自终止周期极化的条件。本文还讨论了自终止方法的计算模型。在实验中，发现极化前的热历史对极化质量有很大的影响。
In this article, poling characteristics and periodic poling of magnesium-oxide-doped lithium niobate (MgLN) are described. Periodic poling was done by the electric field method, with which uniform gratings were produced. The domain wall velocity as a function of poling field was measured and used to determine conditions for self-terminating periodic poling. A computational model for the self-termination method is also discussed here. In the experiment, it was found that thermal history prior to poling has a significant influence on the poling quality.
