摘要：

A multi-position disordered Er3+:Gd2SrAl2O7 single crystal was grown by the Czochralski method. Room temperature polarized spectral properties of the crystal were investigated in detail. The Judd-Ofelt theory was applied to analyze the polarized absorption spectra. The peak stimulated emission cross-sections of the I-4(13/2)-> I-4(15/2) transition reach 0.79 x10(-20) and 1.25x10(-20) cm(2) for sigma and pi polarizations, respectively. The gain curves are flat with full widths at half the maximum larger than 60 nm. Fluorescence lifetimes of the I-4(13/2) multiplet for Er3+ ions were fitted to be 4.93 ms and 3.48 ms from measured fluorescence decay curves for bulk and powder samples, respectively. The results show that the Er3+:Gd2SrAl2O7 crystal may be a potential gain medium for a 1.55 mu m laser with low pumping threshold.
