采用固相反应法制备了（Y3-xTmx）Al 5 O 12（x=0，0.18，0.9，1.5，3）多晶陶瓷。通过先进的陶瓷加工工艺，获得了几乎完美的无孔结构和高透明性的掺铥陶瓷。平均晶粒尺寸为15μm，晶界宽度为1 nm。Y2.82Tm0.18Al5O12（6at.%用785 nm钛宝石激光器端面泵浦5 mm × 5 mm ×3.5mm的Tm：YAG陶瓷板条，在2012 nm处获得了725 mW的最大输出功率，斜率效率为36.2%。
Polycrystalline (Y3−xTmx)Al5O12(x=0, 0.18, 0.9, 1.5, 3) ceramics were fabricated by a solid-state reaction method using high-purity micrometer-sized powders. Tm-doped ceramics with an almost perfect pore-free structure and high transparency were obtained by advanced ceramic processing. The average grain size and grain boundary width were 15μm and 1nm, respectively. The Y2.82Tm0.18Al5O12(6at.% Tm:YAG) ceramic slab (5mm×5mm×3.5mm) was end-pumped by a Ti:sapphire laser at 785nm and the maximum output power of 725mW was obtained with a slope efficiency of 36.2% at 2012nm.
