Optical deflectors, as important functional devices, control the light wave propagation and optical beam trajectories in integrated optical systems. Herein, we design a new type of a laser deflector based on the electric-field-induced strain of manganese-doped potassium tantalate-niobate single crystals. The inverse piezoelectric effect and electrostriction under distributed electric fields are employed to create the deflectors in tetragonal and cubic samples, respectively. The maximum deflection angles are 0.13° and 0.09°, respectively, and both samples have frequency responses up to 5 kHz. The impacts of electric-field distributions on the deflection properties are analyzed. This work provides guidance for implementing reflection deflectors based on an electric-field-induced strain.

电场掺杂锰掺杂钽酸铌铌单晶的激光偏转器

光学偏转器作为重要的功能设备，控制着集成光学系统中的光波传播和光束轨迹。本文中，我们基于电场诱导的锰掺杂钽酸铌铌酸钾单晶的应变设计了一种新型的激光偏转器。利用分布电场下的逆压电效应和电致伸缩分别在四边形和立方样品中创建偏转器。最大偏转角分别为0.13°和0.09°，并且两个样本的频率响应高达5 kHz。分析了电场分布对挠度特性的影响。这项工作为基于电场引起的应变实现反射偏转器提供了指导。
