提出了一种分步式制备端泵浦型光纤合束器的新方法。采用模具、热缩管、细丝对合束光纤进行规则合束与固定,合束后的输入光纤束在拉锥前无须扭转,可形成一整根光纤的形态,从而能够与商业切割刀、熔接机等设备兼容。采取此方法得到的7×1型光纤合束器的耐受功率大于1400 W,泵浦耦合损耗低于0.1 dB。测试和分析了封装后合束器的温度分布,光纤聚合物层温升较大,其限制了合束器耐受功率的提升。

A novel technique for end- pumped fiber combiner fabrication by multi- step process was reported. The mould, heat- shrinkable tube and filament were used to combine and fix the fibers. The combined input fiber beam can form a whole fiber without turning around before tapering, and was compatible with the commercial cut knife and welding machine. The fabricated 7 ×1- type fiber combiner had a endurable power of 1 400 W and the pump coupling loss was under 0.1 dB. The temperature distribution of the packaged fiber combiner was measured and analyzed. It shows that the polymer layer has a big temperature rise and limits the endurable power of the fiber combiner.
