Abstract
Yb 3+-doped La 2(WO 4) 3 single crystals were grown by the Czochralski technique. Absorption and fluorescence spectra of the crystal were recorded at the room temperature. The stimulated emission cross-sections of Yb 3+ ions were calculated using the reciprocity method and Fuchtbauer–Ladenburg formula, respectively. The fluorescence decay curves of 2F 5/2 manifold of Yb 3+ ions were recorded at room temperature for both crystal and powder samples. The effect of radiation trapping on the spectroscopic properties is discussed. Comparison with other Yb 3+-doped laser crystals is made. The results show that Yb 3+:La 2(WO 4) 3 crystal is a promising laser material.
