Abstract
Ytterbium (Yb) doped glass is expected as next generation high-performance solid laser material. However, the laser glasses have a problem that the ions-doping-concentration is much lower than crystals. In this study, we make highly-doped Ytterbium-ions glasses (YbF3-BaF2-AlF3-GeO2, YbBAG), and succeeded laser oscillations of 20 mol.% Ytterbium-ions glass. The highly-doped Ytterbium-ions glasses are much suitable for short-fiber or waveguide lasers.
