高分辨率光谱技术为透明（Cr，Nd）：YAG陶瓷的光谱和能量传递特性带来了新的数据。超交换和电偶极相互作用在Cr-Nd能量传递中的作用得到证实，计算的发光量子效率基本上由Nd浓度决定，对于1at.%的Nd，发光量子效率为52 Nd和77%的2at.% Nd.讨论了Cr和Nd浓度对宽带泵浦下激光发射和发热的影响
High resolution spectroscopy brings new data on the spectroscopic and energy transfer properties of the transparent (Cr,Nd):YAG ceramics. The role of joint superexchange and electric dipole interactions in the Cr-to-Nd energy transfer is evidenced and the calculated emission quantum efficiency is essentially determined by the Nd concentration, 52% for 1 at.%Nd and 77% for 2 at.%Nd. The implication of Cr and Nd concentrations on the laser emission and heat generation under broad-band pumping is discussed
