Abstract

The high optical quality Er:Lu₂O₃ and Er,Pr:Lu₂O₃ crystals were grown by Floating zone method. The spectral properties of Er:Lu₂O₃ and Er,Pr:Lu₂O₃ crystals were investigated. After co-doping small concentration of Pr³⁺, the depopulated influence of Pr³⁺ to the NIR emission was much stronger than the MIR emission. The near-infrared and up-conversion fluorescence were significantly quenched. Moreover, the fluorescence lifetime of ⁴I_13/2 abviously decreases from 4.02 ms to 1.71 ms in 7% Er, 0.05% Pr: Lu₂O₃ crystal, and the lifetime ratio is 1.63 with large fluorescence lifetime of ⁴I_11/2 which is desirable lifetime ratio in these crystals. Thus, the spectral performance was significantly improved by co-doping 0.05 at.% of Pr³⁺. The high laser performance at 2.7 μm of 7% Er, 0.05% Pr: Lu₂O₃ crystal is expectable.
