四束激光光轴高精度稳定控制技术

介绍了压电陶瓷快速倾斜镜以及相应的反馈和控制系统研制过程，并对快速倾斜镜进行了详细的性能测试，包括响应速度、动态范围以及闭环分辨率等重要参数。在此基础上，完成了4束激光相干合成时光轴稳定闭环控制实验。实验结果表明：系统闭环控制时，4束激光光轴的均方根抖动均小于1.5 μrad，与开环状态相比，光轴抖动量减小了80%。通过对开闭环控制结果的对比分析发现，远场光斑平均帧峰值提高了3.8倍。

Abstract

The fast steering mirror manufactured by adopting piezoelectric ceramics and corresponding control and feedback systems were introduced in this paper. The performance of each fast steering mirror was tested, including the key parameters of response speed, dynamical range and closed loop resolution. Then the experiment with optical control in coherent beam combining system was done when the power of light extraction of four lasers reached 100 W. The results show that the optical axis jitters of four lasers are all less than 1.5 μrad (RMS) with closed-loop stability control, which decreases by 80% compared to open-loop results, and the average peak-valley value in far-field increases by 3.8 times.
