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 Omega(2) = 6.74 x 10(-20) cm(2), Omega(4) = 1.20 x 10(-20) cm(2), and Omega(6) = 0.66 x 10(-20) cm(2), 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 mu m, are calculated to be about 4.37 x 10(-21) cm(2). The crystal quality is preliminarily tested through a mid-infrared laser emission experiment.
