摘　　要：理论和实验研究了基于TO单管的绿光LD光纤耦合模块。采用Zemax光线追迹软件对该模块进行了光学设计,包括:绿光TO管的快慢轴准直透镜、缩束透镜组与光纤耦合消像差透镜组。将20支单管通过快慢轴空间合束耦合进入芯径400μm光纤,理论上获得98%以上的光纤耦合效率。实验中选取20支工作电流为1.5A,输出功率为1W的520nm绿光TO单管进行实验,通过快慢轴空间合束技术耦合进入芯径400μm、数值孔径0.22的光纤中,获得10.1W的输出功率,光纤耦合效率为84.2%。A fiber-coupled green diode laser module based on TO-Can packaged single emitters is studied theoretically and experimentally.The optics of fast and slow axis collimation,beam expender,and fiber coupling is designed by using ZEMAX optical design software;and then 20 1-W TO-Can packaged single emitters are combined and coupled into a standard fiber with core diameter of 400μm and numerical aperture of 0.22;and more than 98%of the fiber coupling efficiency is achieved by ray tracing.A total of 10.1W continuous-wave output at wavelength of 520nm is achieved with a coupling efficiency of 84.2%.
