摘要

包层泵浦光纤激光器借助半导体激光二极管棒和堆栈得到了迅速的研究和发展[1]。特别是在掺镱双包层光纤激光器和高质量光束M2≈1的情况下，这些光纤激光器的功率转换效率高达约80%。光纤激光器的输出功率取决于泵浦光能强耦合到双包层光纤内包层的程度。本文介绍了一种基于单模光纤的高效泵浦光束组合器。

Pump beam combiner based on single mode fibres

Cladding pumped fibre lasers have been rapidly researched and developed with help of semiconductor laser diode bar and stack [1]. Especially these fiber lasers showed a high power conversion efficiency of about ∼80% in case of Yb-doped double clad fiber laser and a high-quality beam of M2 ≈ 1. Output power of a fiber laser is determined by how much a pump light can be intensely coupled into an inner cladding layer of a double clad fiber. In this paper, we introduce an efficient pump beam combiner based on single mode fibres.
