Paper Abstract

The output characteristics of fiber lasers built with large-mode-area(LMA) Yb3+-doped double-clad PCF are experimentally investigated. The gain fiber used in the experimental setup is a LMA Yb3+-doped double-clad PCF, which contains an Yb3+-doped core of 23μm in diameter and a holy inner clad of 420μm in diameter. In the forwardoutput configuration the maximum output is 3.43W and the slope efficiency is 34.6%. At the same pump power, the maximum output in the backward-output configuration is 3.63W and the slope efficiency is 38%. The spectra show that the fiber lasers in both forward-output and backward-output configurations produce multi-wavelength output in a range from 1067nm to 1076nm and unstable. Single wavelength output at 1067.5 nm with a FWHM of about 0.2nm is demonstrated by using a dual-end-output configuration, and a maximum output of 4.25W with a slope efficiency of 44.1% is obtained.
