Abstract
We report on a comprehensive spectroscopic study of monoclinic Eu:KLu(WO4)2 crystal concerning its potential applications in red lasers. Optical absorption and stimulated-emission cross-section spectra are determined for this crystal for the principal light polarizations, E || Np, Nm and Ng. The maximum ÏSE corresponding to the 5D0â7F4 transition is 1.78Ã10â20Â cm2 at 703.5Â nm (for E || Nm). Spectroscopic properties of Eu:KLu(WO4)2 are modeled within the conventional Judd-Ofelt theory, as well as its modification for systems with an anomalously strong configuration interaction (ASCI), yielding absorption oscillator strengths, luminescence branching ratios for 5DJâ7FJ' transitions and radiative lifetimes of the 5DJ states. Photoluminescent properties of Eu:KLu(WO4)2 are studied under UV/visible excitation. Polarized Raman spectra are measured for Eu:KLu(WO4)2.
