Static and dynamic effects in sensitized laser crystals

摘要

Abstract: The mutual static crystal field perturbations produced by near sensitizer and activator ions shift the energy levels and modify the radiative and energy transfer characteristics. The selective and discrete nature of these effects transforms the ensembles of sensitizer and activator ions into inhomogeneous systems and modify the spectral and temporal characteristics of emission from activator ions in sensitized laser crystals. These effects are exemplified for Cr$+3$PLU$/ or Fe$+3$PLU$/ sensitized emission of Tm$+3$PLU$/:YAG.!10
