英文摘要AbstractA new laser crystal, Cr/Er/Pr:CaLu0.2La0.8Ga3O7 (Cr/Er/Pr:LuCLGO), was successfully grown by the Czochralski method for the first time. The structural parameters of Cr/Er/Pr:LuCLGO crystal were determined by the x-ray Rietveld refinement method. Optical absorption, fluorescence spectra and lifetime decay profiles were measured for the crystal. The co-doped Cr3+ ion expands the absorption cross-section considerably for 400–700 nm bands, which is beneficial for xenon lamp pumping. Also the co-doped Pr3+ ions decrease the population of the Er3+:4I13/2 energy state effectively. The energy transfer efficiencies of the Er3+:4I11/2 → Pr3+:1G4 and Er3+:4I13/2 → Pr3+:3F4 processes were calculated, showing that Pr3+ ions can play an important role as deactivators for Er3+ ions. Furthermore, the energy transfer mechanisms among Cr3+, Er3+ and Pr3+ ions were studied. The results suggest that Cr/Er/Pr:LuCLGO crystal is a new promising laser medium for 2.7 μm xenon lamp pumping solid-state lasers.
