摘要
针对两种不同激励情况,分别对5芯平行阵列芯光纤的超模进行了理论计算,并对其输出场强度分布进行了实验研究。通过对比5芯平行阵列芯光纤超模远场强度分布,分析了两种不同激励情况下输出各超模的光束质量。研究结果可为高功率光纤激光器、出射光斑为特定形状的光纤激光器的设计提供理论依据,对其他类似微结构光纤在激光器领域的应用具有借鉴意义。
The theoretical prediction and experimental study of 5-core-linear-array fiber are implemented in this paper according to two different excitation methods.The far field supermode distributions of 5-core-linear-array fiber are calculated and the beam qualities under two different excitation methods are also analyzed.The results may provide a basis for high power fiber lasers or for fiber lasers which have particular spot shape and are also helpful for similar microstructure fibers applied in laser areas.
