摘　　要：随着半导体激光器光源在激光加工领域的应用不断拓展,研制高耦合效率的半导体激光器光纤耦合模块变得十分重要。为了进一步提高光纤耦合激光二极管模块的输出功率,本文应用ZEMAX光学设计软件进行仿真模拟,将12只波长为808 nm、输出功率为10 W的单管半导体激光器通过合束方法高效率耦合进光纤。耦合光纤芯径为150μm、数值孔径为0.22,光纤输出功率为116.2 W,耦合效率为96.8%。With the continuous development of high power semiconductor lasers in the field of laser processing,semiconductor laser fiber coupling modules with high coupling efficiency have become more flexible for most applications.In order to further increase the output power and brightness of laser diodes,a 808 nm wavelength fiber coupling module with 12 single-emitter laser diodes has been designed using ZEMAX optical design software,each single-emitter laser diode has an output power of 10 W with a 200 μm wide emission aperture.The core diameter of output fiber is set as 150 μm with a numerical aperture of 0.22.Finally,the simulated result indicates that the module will have an output power of 116.2 W with a coupling efficiency of 96.8%.The result is a good guidance for the practical application,thus further expanded the application field of laser diode.
