Paper Abstract

We fabricated and reported a pedestal fiber with Yb/Ce-codoped aluminosilicate (Al2O3-SiO2) core and germanosilicate (GeO2-SiO2) pedestal. This newly-optimized chelate precursor doping technique enables us to make homogeneous large-core pedestal fiber with strong pump absorption from Yb3+ ions about 3.66dB/m at 915nm. The fiber core was homogeneously doped with 4450ppm Yb3+, 11600ppm Al3+ and 1800ppm Ce3+, and surrounded by pedestal layers with 25000ppm Ge4+. The results indicate all-gas-phase chelate precursor doping technique is highly competitive for the fabrication of pedestal fiber towards narrow-linewidth fiber laser.
