✦ Synopsis

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 power of entering fiber is 2731.8 mW, the maximum output power is 518.4 mW, and the slope efficiency is 19%. The relationship between the output power and the splitting ratio of the output coupler is also studied in this paper. © 2004 Wiley Periodicals, Inc.

## Abstract We propose and demonstrate a novel, all‐fiber and wavelength tunable Er^3+^/Yb^3+^ co‐doped cladding‐pumped fiber‐ring laser, which utilized amplified spontaneous emission (ASE) as a secondary source so that it can operate in L‐band. The lasing threshold can be reduced to 30% by reflect
