摘　　要：介绍了大功率激光两分束无源耦合器的优化设计原理及方法,采用芯径φ105/125阶跃多模纯石英光纤,设计、试制成大功率激光两分束无源耦合器。用小型化固体激光器和LPE-1B激光能量/功率计,测定了两分束器的激光能量耦合、传输参数,结果表明总耦合率达到81.27%。The optimum design principle and method of passive coupler with two-way splitter for high-power laser were introduced. Using φ105/125, stepped index, multi-mode pure quartz optical fibers, the passive couple with two-way splitter was developed. By small-sized solid laser and LPE-1B laser energy/power meter, etc., the laser energy coupling and transmitting parameter of energy were measured. Result showed that the total coupling efficiency can reach up to 81.27%
