Abstract :
We present a compact high-power continuous-wave tunable neodymium-doped double cladding fiber laser operating on three-level 4F32/-I92/ transition with a maximum output power up to 810 mW. At 926.7 nm, it has a maximum slope efficiency of 49.3% against absorbed 808-nm pump. By compressing the fiber Bragg grating, 15-nm tuning range is achieved.
