摘要：
A new, highly efficient and power scalable pump scheme for 3 mu m class fiber lasers is presented. Using the free-running 2.8 mu m emission from an Er3+ -doped fluoride fiber laser to directly excite the upper laser level of the H-6(13/2)-> H-6(15/2) transition of the Dy3+ ion, output at 3.04 mu m was produced with a record slope efficiency of 51%. Using comparatively long lengths of Dy3+-doped fluoride fiber, a maximum emission wavelength of 3.26 mu m was measured. (C) 2016 Optical Society of America
