We report on a detailed revision of the spectroscopic properties of Er3+ ions in the cubic sesquioxide host crystals R2O3 (R = Y, Lu and Sc). The 4f-4f transition probabilities are calculated by applying a modified Judd-Ofelt theory accounting for co

Stimulated-emission cross-sections for the 4I11/2→4I13/2 and 4I13/2→4I15/2 transitions of Er3+ ions in three cubic sesquioxides Y2O3, Lu2O3 and Sc2O3 are revised. The transition probabilities in emission are determined using the Judd-Ofelt theory
