摘要：

The 1.5 mu m emission from Er3+ ions continues to be of current interest for applications in optical communications and eye-safe solid-state lasers. Recently, significant attention has been focused on the development of 1.5-1.6 mu m Er3+ solid-state lasers with resonant pumping of the I-4(13/2) <-> I-4(15/2) transition. The motivation for resonantly pumped Er3+ lasers lies in the reduced thermal load, which is critical for high power laser application. In this work we present results of the infrared optical properties of polycrystalline ceramic Er:YAG and Er:KPb2Cl5 including absorption and emission studies, lifetime measurements, and calculations of 1.5 mu m emission cross-sections using the reciprocity and Fuchtbauer-Ladenburg methods.
