Abstract

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 × 10−7 cm2 s−1 for a sample containing 8.3 × 1020 cm−3 Tm3+ ions.
