摘要
yb^3＋-doped new gallium-lead-germanate glass is presented. Thermal stability, spectroscopic and laser performance parameters of the yb^3＋-doped new gallium-lead-germanate glass are calculated. The results show that the yb^3＋-doped new gallium-lead-germanate glass has good thermal stability （△T =198℃）, high stimulated emission cross section （0.79pm^2）, and long fluorescence lifetime （1.46ms）. Compared with other Yb^3＋-doped glass hosts, the yb^3＋-doped new gallium-lead-germanate glass has better laser performance parameters and laser properties, indicating that yb^3＋-doped new gallium-lead-germanate glass is a promising laser material for short pulse generation in diode pumped lasers, short pulse generation tunable laser, high-peak power and high-average power lasers.
