【摘要】：光纤激光同带抽运方案具有泵浦亮度高、量子亏损小等优势,有着巨大的功率提升潜力,是近年来国际上的研究热点。1018nm光纤激光可作为高功率掺镱光纤激光器的高效同带抽运源,但是单个1018nm光纤激光器输出功率有限,光束合成是突破这一局限的重要方案。基于19台单模1018nm光纤激光器和一个19×1光纤功率合束器,搭建了一套全光纤结构激光合成系统,实现了5kW的1018nm合成激光输出。
[Abstract]:The optical fiber laser co-band pumping scheme has the advantages of high pumping brightness and small quantum loss, and has great power enhancement potential. 1018 nm fiber laser can be used as an efficient co-band pumping source for high power ytterbium doped fiber lasers, but the output power of a single 1018nm fiber laser is limited, and beam synthesis is an important way to break through this limitation. Based on 19 single-mode 1018nm fiber lasers and a 19 脳 1 fiber power synthesizer, an all-fiber structure laser synthesis system is built, and the 1018nm synthesis laser output of 5kW is realized.
