摘　　要：开展了基于同带抽运的高功率、低量子亏损的掺镱光纤放大器实验研究.搭建了一台输出功率为21W的1018nm短波长掺镱光纤激光器,并利用其对双包层掺镱光纤进行同带抽运,获得18.6W的1080nm波段激光输出,光-光转换效率高达90.86%.We show experimentally that a tandem-pumped Yb-doped fiber amplifier with high power and low quantum-defect can be reached. And a high power 21 W output power at 1018 nm is demonstrated finally. We use this 1018 nm fiber laser as a pumping source of the 1080 nm fiber laser to demonstrate the tandem-pumped double-cladding Yb-doped fiber amplifier, and obtain an output power of 18.6 W at 1080 nm with a slope efficiency of 90.86%.
