Thermal Stability and Spectroscopic Properties of Yb^3＋ -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-germinate glass has good thermal stability (Delta T = 198 degrees C), high stimulated emission cross section (0.79 pm(2)), and long flourescence lifetime (1.46 ms). Compared with other Yb3+-doped glass gallium-lead-germinate glass has better laser performance parameters and laser properties, indicating that Yb3+-doped new gallium-lead-germinate 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.
