We present the results of measurements of the time evolution of the fluorescences at wavelengths between 400 and 2500 nm, emitted from an optically pumped Tm,Ho:YAG crystal in response to pulsed excitation at 785 nm. The measurements have been performed as a function of the pumping laser fluence. Comparison of the experimental results with the predictions of a rate equation model of this system has permitted to establish precise values for the rate parameters governing the relevant ion-ion interaction processes inside the crystal.

Abstract
We present the results of measurements of the time evolution of the fluorescences at wavelengths between 400 and 2500 nm, emitted from an optically pumped Tm,Ho:YAG crystal in response to pulsed excitation at 785 nm. The measurements have been performed as a function of the pumping laser fluence. Comparison of the experimental results with the predictions of a rate equation model of this system has permitted to establish precise values for the rate parameters governing the relevant ion-ion interaction processes inside the crystal.File in questo prodotto:
