Spectroscopic studies of Tm: Ho-YAG crystals were performed, with a detailed analysis of the temporal evolution of the fluorescence at 2.09 μm emitted in response to short laser pulse excitation at 785.5 nm. All the fluorescence intensity temporal profiles showed a strong dependence on pumping laser fluence. A considerable decrease of the effective lifetime and of the build-up time has been observed for increasing values of pumping laser fluence. © 1994.
