Direct calculation of lanthanide optical transition intensities Nd3+:YAG
The influence of Coulomb and spin-orbit interactions on one-photon transitions within the 4f3 configuration of Nd3+ in YAG is taken into account by a “direct” calculation, which explicitly evaluates the eigenstates of 4f3 and 4f25d. The interconfigurational crystal-field parameters are fitted to the experimental data and the traditional one-electron intensity parameters are retained to account for non-crystal-field mechanisms. A small but significant improvement in the fit is obtained.
