Thermal Stability and Spectroscopic Properties of Yb³⁺-Doped New Gallium--Lead--Germanate Glass

Yb³⁺-doped new gallium--lead--germanate glass is presented. Thermal stability, spectroscopic and laser performance parameters of the Yb³⁺-doped new gallium--lead--germanate glass are calculated. The results show that the Yb³⁺-doped new gallium--lead--germanate glass has good thermal stability (ΔT=198°C), high stimulated emission cross section (0.79pm²), and long fluorescence lifetime (1.46ms). Compared with other Yb³⁺-doped glass hosts, the Yb³⁺-doped new gallium--lead--germanate glass has better laser performance parameters and laser properties, indicating that Yb³⁺-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.
