Step-index high-absorption Yb-doped large-mode-area fiber with Ge-doped raised cladding

Step-index high-absorption Yb-doped large-mode-area fiber with Ge-doped raised cladding

We report an all-solid large-mode-area (LMA) step-index fiber offering high absorption and low core numerical aperture (NA) by introducing a highly ytterbium-doped P:Al core and germanium-doped cladding. The fiber provides core absorption of ∼1200  dB/m at 976 nm with a low 0.07 core NA, due to the...
