A diode-side-pumped Nd:YAG ceramic slab laser with a high power output is presented. An average power of 526 W is achieved at 1064 nm with a repetition rate of 120 Hz and a pulse width of 180 μs from a 93mm × 52mm × 8 mm ceramic slab at a pump power of 1928 W, corresponding to an optical-to-optical efficiency of 27.3%.

采用真空烧结固相反应法, 分别制备了不添加和添加烧结助剂(正硅酸乙酯TEOS和MgO)的Pr:LuAG ( Pr: Lu 3 Al 5 O 12 )陶瓷, 研究发现添加烧结助剂烧制的Pr:LuAG陶瓷在可见光区的直线透过率可达~80%, 不添加烧结助剂的陶瓷光学透过率降低(可见光区~70%, 2 mm厚), 但光输出提高了5倍(为1196 pe/MeV), 衰减快分量比例可达73%, 能量分辨率8.4%。将Pr:LuAG陶瓷加工成1.9 mm×1.9 mm×1.0 mm的陶瓷阵列组装探测器模块, 用4×4陶瓷阵列单元实现了二维散点图成像, 所成散点图清晰可辨。经过平台测试, 相同耦合条件下本实验制备的Pr:LuAG陶瓷成像质量优于商用BGO (Bi 4 Ge 3 O 12 )单晶, 结果显示Pr:LuAG陶瓷有望应用于PET (Positron Emission Tomography) 级别核医学成像系统。采用真空烧结固相反应法, 分别制备了不添加和添加烧结助剂(正硅酸乙酯TEOS和MgO)的Pr:LuAG ( Pr: Lu 3 Al 5 O 12 )陶瓷, 研究发现添加烧结助剂烧制的Pr:LuAG陶瓷在可见光区的直线透过率可达~80%, 不添加烧结助剂的陶瓷光学透过率降低(可见光区~70%, 2 mm厚), 但光输出提高了5倍(为1196 pe/MeV), 衰减快分量比例可达73%, 能量分辨率8.4%。将Pr:LuAG陶瓷加工成1.9 mm×1.9 mm×1.0 mm的陶瓷阵列组装探测器模块, 用4×4陶瓷阵列单元实现了二维散点图成像, 所成散点图清晰可辨。经过平台测试, 相同耦合条件下本实验制备的Pr:LuAG陶瓷成像质量优于商用BGO (Bi 4 Ge 3 O 12 )单晶, 结果显示Pr:LuAG陶瓷有望应用于PET (Positron Emission Tomography) 级别核医学成像系统。Pr:LuAG ceramics were fabricated by a solid state reaction method using vacuum sintering with or without sintering aids (TEOS and MgO). The inline transmittance of the Pr:LuAG ceramics sintered with sintering aids reached similar to 80% in visible light range, while the ceramics without sintering aids were 5 times higher light output (1196 pe/MeV) and faster decay (73% fast decay component) although lower transmittance in visible light region (similar to 70%, 2.0 mm thick) comparatively with the energy resolution of 8.4%. The Pr:LuAG cermics were cut and polished to 1.9 mm x1.9 mm x 1.0 mm pixels to form ceramics arrays, by using the 4x4 ceramics arrays, 2D mapping was accomplished. The position signals were clearly identified, which were better than that of commercial BGO (Bi4Ge3O12) crystals. It is proved that Pr:LuAG ceramics is promising in PET (Positron Emission Tomography) imaging.
