Yb:YAG晶體,中文名摻鐿釔鋁石榴石，是應用前景廣闊的激光工作物質(zhì)。
Yb:YAG晶體或摻鐿釔鋁石榴石晶體更 適合激光二極管泵浦系統(tǒng)，并不適合傳統(tǒng)的摻釹激光系統(tǒng)的泵浦結(jié)構(gòu)。Yb:YAG晶體（Yb:YAG）或摻鐿釔鋁石榴石可輸出0.94 μm激光，與傳統(tǒng)的Nd:YAG晶體相比，Yb:YAG晶體或摻鐿釔鋁石榴石具有更大的吸收帶寬,更長的上能級壽命，3-4倍更低的單位泵浦功率熱負荷。
Yb:YAG晶體或摻鐿釔鋁石榴石在高功率半導體泵浦激光器領域，被人們認為是取代Nd:YAG 晶體的**選擇。

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.
