Abstract

An all-fiberized broadband superfluorescent source based on a distributed side-coupled cladding-pumped Yb-doped fiber is demonstrated. A recorded 102 W combined output power is obtained with the angle-cleaved output ends. The bandwidth is larger than 10 nm. The power scalability of the superfluorescent source is analyzed numerically. It is found that, besides the optical feedback, the active fiber length is another key. The result shows that, by optimizing the active fiber length, it is promising to realize a 600 W superfluorescent source with this scheme.

摘要

展示了一种基于分布式侧面耦合包层泵浦掺镱光纤的全光纤化宽带超荧光源。通过角切割输出端获得了记录的102瓦组合输出功率。带宽大于10纳米。对超荧光源的功率可扩展性进行了数值分析。发现除了光反馈外，有源光纤长度是另一个关键因素。结果表明，通过优化有源光纤长度，有望用该方案实现600瓦的超荧光源。
