10-W Random Fiber Laser Based on Er/Yb Co-Doped Fiber

Abstract

In this study, we presented a 1550 nm, high-power, high-efficiency random fiber laser. A method, utilizing the single-mode erbium-ytterbium co-doped fiber with proper length and the highly reflective fiber Bragg grating with wide reflection bandwidth, is used to surmount the generation of Yb-ASE and low slope efficiency. More than 10 W output power is achieved, with a slope effi-ciency of 36.7% and single transverse mode output. The random fiber laser stably operates without significant amplitude fluctuation under maximum power, and which can provide a high-performance light source for a variety of applications.
