摘　　要：利用Nd:YAG脉冲激光器的二倍频光及三倍频光激励的香豆素480染料激光作为激发光源直接测量钛蓝宝石(Ti^(3+):Al_2O_3)晶体的光声信号,确定它的绝对荧光量子效率。Using the second harmonic of a pulsed Nd: YAG laser and the coumarin 480 dyelaser pumped by the third harmonic of a pulsed Nd: YAG laser, we measured the Ti:Al_2O_3 crystalphotoacoustic signal directly, and determined its abstract fluorescence quantum efficiency.
