Energy Transfer in Cr, Tm:YAG
We describe a systematic analysis of energy transfer processes in crystals of YAG doped with varying concentrations of Cr and Tm. We use both spectral measurements and measurements of the temporal response to pulsed excitation to give independent determinations of the microscopic interaction parameter for Cr to Tm transfer. We discuss the different factors in influencing the temperature dependence of the Cr to Tm transfer. Finally, we determine the dependence of the Tm cross-relaxation rate on Tm concentration.
