摘　　要：简介了大功率二极管激光器垂直阵列巴条(Bar)间准直光束指向精度问题,及其对激光器垂直阵列输出光束的影响。采用单透镜远场探测系统对激光器垂直阵列远场光斑进行采集,搭建了实验测试装置。结合光斑强度质心算法对实验室封装的20巴条连续输出2kW二极管激光器垂直阵列进行了测量,测试结果为巴间准直光束指向精度±1.7mrad,结合二极管激光器封装工艺分析了测试结果,并对该测量方法进行了讨论分析,提出了优化该测试方法的途径。High power diode laser vertical stack＇s co laser beam are introduced. The experimental device the light spot of the vertical stacking. By combinin stacking diode laser, the results of collimation beam＇s llimated beam pointing error and the influence of the pointing on the is built, and single anastigmatic far field lens are adopted to collect g the centroid arithmetic measured continuous work 2 kW vertical pointing accuracy was ±1.7 mrad. The errors of the metrical method are analyzed and some routes are optimized to improve the metrical method.
