Yb: LuAG

LuAG (Lutetium Aluminum Garnet) is of particular interest as a material for diode pumped solid-state lasers employing active ions such as Yb, Tm, Er, and Ho. This host has the smallest lattice constant of the rare earth garnets and the resulting crystal field in LuAG yields narrower linewidths and higher absorption and emission cross-sections. The net effect is higher efficiency laser devices.
