Yb:LuAG是應用前景廣闊的激光工作物質,Yb:LuAG更適合激光二極管泵浦系統，并不適合傳統的摻釹激光系統的泵浦結構。Yb:LuAG晶體或摻鐿釔鋁石榴石可輸出0.94 μm激光，與傳統的Nd:YAG晶體相比，Yb:LuAG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:LuAG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。

Yb:LuAG

Undoped YAG has higher thermal conductivity compared to undoped LuAG. Increasing Yb³⁺ doping leads to a drop of in thermal conductivity. In Yb:YAG thermal conductivity decreases to almost half of its initial value, while Yb:LuAG displays a drop of only 10%. Heavily doped Yb:LuAG can be advantageously used in thin disc lasers.
