Abstract

A narrow line width, tunable, and highly efficient fiber laser based on Er^3+^/Yb^3+^ co‐doped double‐clad fiber with the maximum output power of 438 mW and a slope efficiency of ∼16% has been demonstrated. By using a fiber Bragg grating (FBG) as a narrow band reflector, 3‐dB line width of the output laser could be as narrow as 0.04 nm over the whole tuning range, and by compressing or stretching the FBG, wavelength tunable range of 4.0 nm was realized. In the experiment, we also found that there existed an optimum splitting ratio of the output coupler, at which the maximum output power could reach ∼647 mW. © 2006 Wiley Periodicals, Inc.
