提出了一种在室温下外加脉冲电场对钽酸锂单晶进行周期性极化的方法。研究了反转畴生长与开关电流和开关时间的关系。反转畴的生长可以通过脉冲场的持续时间来控制。在0.3 mm厚的LiTaO 3板上通过部分开关制备了周期为Λ <$8 μm的畴结构。
A method of periodically poling LiTaO3 single crystal at room temperature by applying an external pulsed field is proposed. The relationship between the growth of inverted domains and switching current as well as switching time has been studied. The growth of inverted domains can be controlled by the duration of the pulsed field. The domain structure with period Λ≳8 μm has been fabricated in a 0.3‐mm‐thick plate of LiTaO3 by partial switching.
