摘　　要：用几何光学的方法计算了透镜导管的慢轴和快轴方向的光束分布。结果表明，用于固体激光器泵浦的高功率激光二极管阵列的非连续分布的激光束通过透镜导管后可以获得平滑而均匀的光场分布。基于这种分析，我们设计了两种结构的透镜导管，用激光二极管阵列实验测得未镀抗反膜的透镜导管的耦合效率高达８４％。Based on ray tracing in slow and fast axis directions,the output beam profiles of the lens duct is calculated when light beams from laser diode arrays pass through it,and the results demonstrate that a smooth and symmetric beam can be obtained.Based on this analysis we have designed two type lens ducts and the coupling efficiency as high as 84% with quasi CW laser diode array was obtained for AR uncoated lens duct.
