Paper Abstract

Single crystals of LaMgAll1O19 (magnetoplumbite-like structure) doped with Pr3+, Sm3+, Dy3+, Ho3+, Er3+ have been obtained by the flame fusion process. For each ion, the limit solubility has been determined. Optical absorption, emission and fluorescence excitation have been performed on cleavage platelets and the position of the fluorescent levels determined. The possible sensitization of the two Pr3+ fluorescent levels (3P0 and 1D2) by Dy3+ and Sm3+ respectively has been investigated. Energy transfer is important for instance if the lamp pumping of these solid state lasers is considered.
