    摘要:

    利用仿真软件分析了侧面泵浦(N+1)×1耦合器不同泵浦臂数量对侧面泵浦耦合器效能的影响,并在实验中验证了分析结果,得到侧面泵浦耦合器中耦合效率随着泵浦臂数量增多呈下降趋势这一结论.根据这一结论制作了侧面泵浦(2+1)×1耦合器,输出泵浦功率681 W,输出功率为同泵浦源(1+1)×1耦合器的两倍,有效地减少了因泵浦臂数量影响造成的耦合器总功率缺失.

    Abstract:

    The impact of (N+1)×1 coupler pump arm numbers on the pump coupling efficiency was numerically studied firstly. It is shown that pump coupling efficiency decreases with more pump arms built on the coupler, yet in a slightly decreasing manner. According to the simulation results, side-pumped (1+1)×1 and (2+1)×1 couplers were made. The total output power of the (2+1)×1 coupler is about 681 W, almost two times that of the (1+1)×1 coupler, enhancing the pump light injection capacity of the fiber laser system significantly.
