合成了一系列具有良好热稳定性的Ho 3 +/Tb 3+共掺氟铟酸盐玻璃,研究了Tb 3+对Ho 3+:3.9 μm发光的钝化作用。在888 nm半导体激光器(LD)的激发下,获得了3.9 μm的有效发射增强。计算了Judd-Ofelt(J-O)强度参数和辐射性质,以评估光谱性质。可能的能量转移过程导致排放加固进行了讨论。Tb ~(3+)的掺入使样品的自发跃迁几率和峰值发射截面增大。这一分析支持了Ho 3 +/Tb 3+共掺氟铟酸盐玻璃是一种潜在的用于高效3.9 μm光纤激光器的激光材料的结论。
A series of Ho3+/Tb3+co-doped fluoroindate glasses with good thermal stability have been synthesized to study the deactivation effects of Tb3+on the Ho3+: 3.9 μm emission. Efficient 3.9 μm emission enhancement is obtained under excitation by an 888 nm laser diode (LD). The Judd-Ofelt (J-O) intensity parameters and radiative properties are calculated to evaluate the spectroscopic properties. Possible energy transfer processes resulting in emission reinforcement are discussed. A higher spontaneous transition probability and larger peak emission cross section are achieved with the inclusion of Tb3+. This analysis supports the conclusion that Ho3+/Tb3+co-doped fluoroindate glass is a potentially useful laser material for highly efficient 3.9 μm fiber lasers.
