Abstract
Ion-lattice coupling between different local (impurity) - phonon (lattice) modes is considered the main factor that determines the dynamics of nonradiative processes in impurity-doped solid-state lasers. Although critical, this problem is not yet completely understood. This study investigates the phonons involved in nonradiative processes in Cr:Mg2SiO4 by using time-resolved Raman scattering and upconverted hot luminescence. The results are correlated with data provided by resonance Raman spectra for Cr4+ local modes to obtain a criterion for local mode coupling to lattice modes.
