摘要

In this paper, a cladding-pumped erbium-ytterbium co-doped random fiber laser (EYRFL) operating at 1550 nm with high power laser diode (LD) is proposed and experimentally demonstrated for the first time. The laser cavity includes a 5-m-long erbium-ytterbium co-doped fiber that serves as the gain medium, as well as a 2-km-long single-mode fiber (SMF) to provide random distributed feedback. As a result, stable 2.14 W of 1550nm random lasing at 9.80 W of 976 nm LD pump power and a linear output with the slope efficiency as 22.7% are generated. This simple and novel random fiber laser could provide a promising way to develop high power 1.5 μm light sources.
