An amplifier model based on the Yb-doped segment cladding fiber (SCF) is proposed, and three contributions to heat source are taken into account in the proposed mode. Results show that distribution of heat load is dependent on pumping scheme and has impacts on modal gain competition. In addition, SCF presents better HOMs filtering effect and higher amplification efficiency of LP01 when compared with the conventional step index fibers.

热负载下有源段包层光纤的激光性能


提出了一种基于掺镱分段包层光纤（SCF）的放大器模型，并在该模型中考虑了热源的三种贡献。结果表明，热负荷的分布取决于泵送方案，并对模态增益竞争有影响。此外，与传统阶跃折射率光纤相比，SCF呈现出更好的HOMs滤波效果和LP01更高的放大效率。
