摘要：

We report what is to our knowledge the first direct measurement of spatial energy migration among the Tm3+ ions in a Tm,Ho:YAG crystal at room temperature. Four-wave mixing techniques were used to establish and probe transient laser-induced population gratings in the Tm3+ ions. The grating decay rate was measured as a function of the grating spacing. The results show the presence of spatial energy migration among the Tm3+ ions, and the diffusion coefficient of this process was measured to be 4 x 10(-7) cm2 s-1 for a sample containing 8.3 x 10(20) cm-3 Tm3+ ions.
