制备了不同P_2O_5：TeO_2比和Yb ~（3+）浓度的掺镱磷碲酸钠玻璃。新Yb基质的物理性质有利于激光应用。该玻璃具有高的吸收和发射截面以及较高的Yb ~（3+）：2F_5/2rarr_2F_7/2跃迁寿命。用两种不同的方法计算了发射截面，并进行了比较。这些掺Yb ~（3+）玻璃的激光参数优于许多已报道的玻璃和晶体，使它们有可能在~1 μ m波长范围内制备高功率激光器和宽带光放大器
Ytterbium-doped sodium phospho-tellurite glasses are made with different P2O5:TeO2 ratio, and Yb3+ concentrations. Physical properties of the new Yb hosts are favorable for laser applications. The glasses show high absorption and emission cross sections and higher lifetime of Yb3+:2F5/2rarr2F7/2 transition. The emission cross sections are calculated using two different methods and compared. The laser parameters of these Yb3+ -doped glasses are better than many reported glasses and crystals making them potential to fabricate high power laser and broadband optical amplifier in the wavelength region around ~1 mum
