中文摘要：
制备了一种新的Yb3＋掺杂镓铅锗玻璃，测试了吸收光谱和荧光光谱，研究了基质材料的热稳定性能，计算了光谱和激光性能参数。发现Yb3＋掺杂镓铅锗玻璃具有较好的热稳定性能（△T=198℃），高的受激发射截面（0．79pm2）和长的荧光寿命（1．46ms）。与其它Yb3＋掺杂基质玻璃相比，Yb3＋掺杂镓铅锗玻璃具有更好地激光性能参数和激光性质，表明Yb3＋掺杂镓铅锗玻璃是一种新型的Yb3＋掺杂包层光纤激光器潜在的基质材料。
英文摘要：
Yb3＋-doped new gallium-lead-germanate glass was prepared, the absorption and luminescence spectra were tested, thermal stability of host material was studied and spectroscopic and laser performance parameters were calculated. The results show that Yb3＋-doped new gallium-lead-germanate glass has good thermal stability （△T=198℃）, high stimulated emission cross-section （0.79 pm2） and long fluorescence lifetime （1.46 ms）. The Yb3＋-doped gallium-lead-germanate glass has better laser performance parameters and laser properties than other Yb3＋-doped glass hosts, which indicates that Yb3＋-doped new gallium-lead-germanate glass is a potential host material for new-style Yb3＋-doped double cladding fiber laser.
