摘要：
A Large-Mode Area (LMA) single-mode Ytterbium-doped fiber amplifier with distributed narrow passband filtering is demonstrated. The fiber passband is similar to 40nm wide and centered at 1070nm for efficient filtering of both short- and long-wavelength Amplified Spontaneous Emission (ASE) as well as Stimulated Raman Scattering ( SRS). The fiber design provides Higher-Order Mode ( HOM) suppression and is polarization maintaining. It has a mode field diameter of 27 mu m and exhibits a slope efficiency of >60%.
