摘要：

The spectroscopic properties of various Ni2+-doped garnets and perovskites are investigated. In the garnets Ni2+ is found to occupy both octahedral and tetrahedral sites, whereas in the perovskites only octahedral sites exist. The spectroscopic data indicate, that GGG:Ni,Zr and YAlO3:Ni,Ti are the most promising materials for laser operation. The quantum efficiencies are nearly unity and the emission cross sections are twice that of MgO:Ni. However, laser action has not yet been achieved. The reason may be excited state absorption.
