✦ Synopsis

The C-band is demonstrated to be suitable for pumping L-band erbium-doped fiber laser (EDFL) with a broad pumping band. A high power C-band superfluorescent fiber source (SFS) peaked at 1545 nm with output power of 1.86 W is constructed and utilized as pump source for L-band EDFL. Based on this, an all single-mode-fiber L-band EDFL emitting at 1591.9 nm with 1.19 W output power is obtained. The laser exhibits a high conversion efficiency of 64.0% with a high ASE extinction ratio of 66 dB and a narrow bandwidth of less than 0.08 nm.

## Abstract A novel Er^3+^/Yb^3+^ co‐doped double‐clad fiber‐ring laser, which utilizes amplified spontaneous emission as a secondary pump source in order to operate in L‐band, is demonstrated. Six laser diodes are used to cladding‐pump Er^3+^/Yb^3+^ co‐doped double‐clad fiber. When the pumping pow
