In this paper, a high-speed non-mechanical two-dimensional KTN beam deflector is reported. The scanning mechanism is based on the combination of space charge controlled beam deflection and temperature gradient enabled beam deflection in a nanodisordered KTN crystal. Both theoretical analyses and experimental investigations are provided, which agree relatively well with each other. This work provides an effective way for realizing multi-dimensional high-speed non-mechanical beam deflection, which can be very useful for a variety of applications, including high-speed 3D laser printing, high resolution high speed scanning imaging, and free space reconfigurable laser communications.
本文报道了一种高速非机械二维KTN光束偏转器。扫描机制基于纳米无序KTN晶体中空间电荷控制的光束偏转和温度梯度引起的光束偏转的结合。同时提供了理论分析和实验研究，两者结果较为吻合。这项工作为实现多维高速非机械光束偏转提供了一种有效方法，这对于包括高速3D激光打印、高分辨率高速扫描成像和自由空间可重构激光通信在内的各种应用非常有用。
