Yb:YAG晶体,中文名掺镱钇铝石榴石，是应用前景广阔的激光工作物质。
Yb:YAG晶体或掺镱钇铝石榴石晶体更 适合激光二极管泵浦系统，并不适合传统的掺钕激光系统的泵浦结构。Yb:YAG晶体（Yb:YAG）或掺镱钇铝石榴石可输出0.94 μm激光，与传统的Nd:YAG晶体相比，Yb:YAG晶体或掺镱钇铝石榴石具有更大的吸收带宽,更长的上能级寿命，3-4倍更低的单位泵浦功率热负荷。
Yb:YAG晶体或掺镱钇铝石榴石在高功率半导体泵浦激光器领域，被人们认为是取代Nd:YAG 晶体的**选择。

The Yb³⁺ ion exhibits a small quantum defect and a quasi-three level system with a long upper laser level lifetime (around 1 ms for Yb:YAG), which is important for energy accumulation in Q-switched lasers. The wide luminescence band of Yb³⁺ is advantageous for the generation of sub-picosecond pulses. Yb³⁺ doped crystals do not suffer from luminescence concentration quenching. Their long energy storage lifetime, broad absorption band at 940 nm and very low quantum defect make Yb:YAG and Yb:LuAG crystals superior candidates for diode-pumped high-energy lasers.
