摘　　要：The CW 39.4 W all-fiber LD-clad-pumped Tm^3＋-doped fiber laser output is reported with a slope efficiency of 34% in respect to the pump power. The all-fiber laser is made up by progressively splicing the pigtail fiber, matched FBG fiber and Tin-doped fiber. The reflective FBG and Tm-doped fiber end fresnel reflection build up the laser resonance cavity. Due to the multi-mode FBG as the reflective mirror, the output laser spectrum is multi-peaks at high power output, whereas the total spectrum width is less than 2nm at nearly 1.94μm.The CW 39.4 W all-fiber LD-clad-pumped Tm^3＋-doped fiber laser output is reported with a slope efficiency of 34% in respect to the pump power.
