摘　　要：为获得理想的多尺度量子激光器光束采集结果,提出一种多尺度量子激光器光束采集的高精度控制方法。通过探测器采集光束的二维成像,结合偏振片与晶体改变光束的偏振态;分析偏振态与二分之一波片及四分之一波片的快轴与x轴的夹角,通过将夹角加载到调制器中的灰度图像相对应关系,实现光束采集的高精度控制。测试结果表明,设计方法提高了多尺度量子激光器光束采集精度,控制误差较小,具有较高的实际应用价值。In order to obtain ideal results of multi-scale quantum laser beam acquisition,a high-precision control method of multi-scale quantum laser beam acquisition is proposed.Two-dimensional imaging of the light beam is collected by a detector,and the polarization state of the light beam is changed by combining a polarizer and a crystal.The angle between polarization state and half-wave plate and fast axis and X axis of quarter-wave plate is analyzed,and the high-precision control of beam acquisition is realized by loading the angle into the corresponding relation of gray image in modulator.The test results show that the design method improves the beam acquisition accuracy of the multi-scale quantum laser with small control error,and has high practical application value.
