摘要：

The 30 at.% Ho: BaY2F8 crystals were grown by the Czochralski method, and their spectroscopic properties are analyzed systematically by standard Judd-Ofelt theory. The Judd-Ofelt intensity parameters are estimated to be Ω2=6.74× 10-20cm2, Ω4=1.20× 10-20 cm2, and Ω6=0.66× 10-20cm2, and the fluorescence branching ratios and radiative lifetimes for a series of excited state manifolds are also determined. The emission cross sections with our measured infrared luminescence spectra, especially important for 4.1 μm, are calculated to be about 4.37× 10-21 cm2. The crystal quality is preliminarily tested through a mid-infrared laser emission experiment.
