基于透射体布拉格光栅频谱组束的设计方案,采用半导体激光器作为泵浦源,以双包层Er3+/Yb3+共掺光纤为增益介质,报道了两束光纤激光频谱组束的实验结果。作为一种激光合成方法,在两束光纤激光输出功率分别为0.48W和0.71W、光栅实际衍射效率不到40%的情况下,实现了组束功率为0.56W,绝对组束效率约为47%的组束激光输出。并分析了实验过程中影响组束效率的因素。 Based on the design scheme of the Bragg grating spectral bundle, the experimental results of the two laser fiber bundles were reported using the semiconductor laser as the pump source and the double-clad Er3 + / Yb3 + co-doped fiber as the gain medium. As a laser synthesis method, the output power of two fiber lasers is 0.48W and 0.71W respectively, and the actual diffraction efficiency of the grating is less than 40%, the power of the combined beam is 0.56W, and the absolute recombination efficiency is about 47 % Of the group laser output. The factors influencing the beam efficiency were also analyzed.
