Two optical waves (at 1064 nm) were used to resonantly induce a population grating in a flash-lamp-pumped Nd:YAG rod, and a nonresonant wave (at 1054 or 694 nm) was used to read (with a diffraction efficiency of as much as 1% or 0.3%, respectively) the refractive-index grating caused by the difference in the polarizability of the excited and the unexcited Nd ions. Comparisons of experimental results and numerical calculations gave the dependence of the ratio of the real and the imaginary parts of the resonant susceptibility of Nd:YAG at 1064 nm on the pump power.
使用两束光波（波长为1064纳米）在闪光灯泵浦的钕钇铝石榴石（Nd:YAG）棒中谐振诱导粒子数光栅，并用一束非谐振波（波长为1054或694纳米）读取（衍射效率分别高达1%或0.3%）由激发态和未激发态钕离子极化率差异引起的折射率光栅。实验结果与数值计算的比较给出了1064纳米处Nd:YAG谐振磁化率实部与虚部之比对泵浦功率的依赖关系。
