Description

The line strengths in four polarization directions of the incident radiation of the (8S7/2) →(6P5/2)Γ7, Γ8 and (8S7/2) → (6P7/2)Γ6, Γ7, Γ8 two photon absorption (TPA) transitions of Eu2+ in the perovskite KMgF3 host have been calculated using the third-order Judd-Pooler (JP) formalism. In general, the calculated relative intensities are in good agreement with experiment, except for the ratios between the linear and circular polarizations in the 8S7/2 → 6P7/2 transitions. In particular, the scalar operator term in the third-order spin-orbital correction formula successfully explains nine 8S7/2 → 6P7/2 transitions with different linear polarizations
