测量了Nd 3+在含有各种碱金属和高价态阳离子的碲酸盐玻璃和一系列新的磷碲酸盐玻璃中的光吸收和发射光谱以及荧光寿命。Judd-Ofelt强度参数被确定并用于计算4F 3/2→ 4 I11/2和4F 3/2→ 4 I13/2跃迁的辐射寿命和受激发射截面。几种玻璃的横截面是任何纯氧化物玻璃中最大的。讨论了碲酸盐玻璃的光谱性质与组成的关系及其在激光器中的应用。
Optical‐absorption and emission spectra and fluorescence lifetimes were measured for Nd3+ in tellurite glasses containing various alkali and higher valence state cations and in a series of new phosphotellurite glasses. Judd‐Ofelt intensity parameters were determined and used to calculate radiative lifetimes and stimulated emission cross sections for 4F3/2→4I11/2 and 4F3/2→4I13/2 transitions. Cross sections for several of the glasses are the largest obtained for any pure oxide glass. The dependence of the spectroscopic properties on composition and the application of tellurite glasses for lasers are discussed.
