摘要：

High optical quality Er3+ doped Lu2O3 single crystal with optimum doping concentration was grown by Floating zone (Fz) method. The spectral properties and Judd-Ofelt (JO) analysis were reported. The emission cross-section at 2772 nm was calculated to be 2.47 x 10(-20) cm(2) with FWHM of 188 nm. The fluorescence lifetime of I-4(11/2) and I-4(13/2) energy level was fitted to be 1.62 ms and 4.02 ms. Optimum lifetime ratio (tau(low)/tau(up)) is beneficial to laser operation. Compared with reported Er3+ doped crystal, the larger spectral quality factors Q and low inversion ratio P of 7 at.% Er:Lu2O3 crystal indicate that it has a favorable laser performance for 2.8 mu m laser operation.
