摘　　要：采用柱透镜对 10单元阵列半导体激光器的输出光束进行了有效收集和预准直及与多模光纤之间的耦合实验。激光器采用 80 8nm波长、15 0 μm条宽的发射单元 ,周期为 10 0 0 μm,与 2 0 0 μm芯径平端光纤阵列的耦合效率高达 75 % ,光纤输出功率 7.5 W。分析了影响耦合效率的主要因素。The light output of 10-stripe LD array is effectively collected, pre-collimated with cylindrical lens, and coupled into a bundle of multi-mode fibers. The width of emitting stripe is 150 μm with a period of 1000 μm and the lasing wavelength of the LD array is 808 nm. The coupling efficiency between LD array and 200 μm core-diameter fibers with flat end is as high as 75%, and more than 7.5 WXCW light output from fibers has been achieved. Also the main factors effecting coupling efficiency are analyzed.
