Paper Abstract

The paper discusses the problem of Nd concentration dependence of the emission quantum efficiency in Nd:YAG at low pump intensities, based on a modeling which uses the emission decay data. The measurements on crystalline or ceramic Nd:YAG samples with Nd concentrations up to 9at.%Nd show a marked dependence on concentration, induced by the energy transfer self-quenching. The parameters of ion-ion interactions that determine the transfer are used for an analytical modeling of the concentration dependence of the emission quantum efficiency, which gives a very good description of the experimental data.
