A 43W C-band tunable narrow-linewidth erbium-ytterbium co-doped large-core fiber laser
We report a widely tunable and highly efficient cladding-pumped erbium-ytterbium large-core fiber laser, generating up to 43 W of output power at ~1.5 µm with co-doped a narrow linewidth (0.16 nm full width at half maximum) and a good beam quality (M2 ≤ 1.7). By the use of a tunable narrow-band fibe...

| Summary: | We report a widely tunable and highly efficient cladding-pumped erbium-ytterbium large-core fiber laser, generating up to 43 W of output power at ~1.5 µm with co-doped a narrow linewidth (0.16 nm full width at half maximum) and a good beam quality (M2 ≤ 1.7). By the use of a tunable narrow-band fiber Bragg grating, the laser wavelength was tuned from 1532 nm to 1567 nm, limited upwards by the tuning range of the fiber grating. The overall slope efficiency was 32% with respect to launched pump power. |
