摘　　要：制备多晶、透明的Nd:YAG陶瓷,测量其吸收光谱、发射光谱、荧光光谱及荧光寿命。它展现出的光学特性与单晶的性能几乎一样。但Nd:YAG陶瓷制备方法比单晶的生长技术简单。目前,可制造出大尺寸(现已达直径450 mm×10mm)和高浓度(10%)(原子分数)的Nd:YAG陶瓷。该文对Nd:YAG透明陶瓷的制备技术、光谱特性进行了综合评述,分析了陶瓷的光学性能比单晶好的原因。结果表明,这种Nd:YAG陶瓷比Nd:YAG单晶更具备良好的选择性。Polycrystalline, transparent Nd ： YAG ceramics are fabricated, and their absorption spectra , emission spectra, fluorescence spectrum, and fluorescence lifetime are measured. It exhibits nearly the same spectroscopic properties as those of a single crystal. But the fabrication of Nd：YAG ceramics is much easier as compared with the single--crystal growth method. Large size （now of about 450 mm diameter × 10 available） and high--concentration （10%） Nd：YAG ceramics can be fabricated. The preparation technology , optical properties of ceramics are reviewed. The reasons why ceramics are better than single crystal in optical properties are also analyzed. The results show that this kind of Nd：YAG ceramics is a very good alternative to Nd：YAG single crystal.
