In this paper, we apply this model to the prediction of the steady-state photorefractive space-charge field. We present experimental measurements of induced absorption and beamcoupling gain in BaTiO3:Rh at 1:06 µm, which are consistent with the model. From these data, we determine a set of parameters (with error bars) such as the excitation cross sections and density of rhodium. %G English %L ujm-00118163 %U https://ujm.hal.science/ujm-00118163 %~ UNIV-ST-ETIENNE %~ IOGS %~ CNRS %~ UNIV-PSUD %~ PARISTECH %~ LCFIO %~ LCF_MANOLIA %~ UNIV-PARIS-SACLAY %~ UNIV-PSUD-SACLAY %~ UDL
