Abstract In this paper some spectroscopic properties of Y3Sc2Ga3O12 (YSGG):Cr,Ho, YSGG:Cr,Tm and YSGG:Cr,Tm,Ho are presented. The three lowest energetic manifolds of Ho3+ and Tm3+ in YSGG have been determined at 10 K. Time-resolved fluorescence build-up and decay of the laser active ions was measured in three crystals with different dopant concentrations. The transitions investigated were5I7 →5I8 for Ho3+ near 2000 nm and3H4 →3H6 for Tm3+ near 1800 nm. The data found on time-resolved fluorescence and energy level positions are useful for the discussion of the energy transfer characteristics of the system.
