摘要

研究了介电晶体（复杂氧化物、简单和复杂氟化物）中掺杂的 Nd3+、Ho3+、Er3+ 和 Tm3+ 离子的激光跃迁的受激发射截面与极化率体积之间的关系。通过将掺杂剂的极化率纳入各自的浓度，计算出了含有 Ln3+ 离子的每种晶体的整体极化率。与相同晶格中掺杂的其他 Ln3+ 离子相比，该方法揭示了一系列晶体（如 Y3Al5O12、YAlO3、LiYF4）中 Nd3+ 离子在上述依赖性中的明显不同位置。

Polarizabilities and emission cross-sections of lanthanide laser crystals

The dependence between stimulated-emission cross-sections and polarizability volumes has been studied for laser transitions of Nd3+, Ho3+, Er3+, and Tm3+ ions doped in dielectric crystals: complex oxides, simple and complex fluorides. The overall polarizability of each crystal containing Ln3+ ions has been calculated by inclusion of the dopant polarizability in respective concentration. The applied method has revealed distinctly different positions of Nd3+ ions in the mentioned dependence in a series of crystals, e.g. Y3Al5O12, YAlO3, LiYF4, compared to the other Ln3+ ions doped in the same lattices.
