✦ Synopsis

Single crystals of Yb, Nd: KLu(WO 4 ) 2 (Yb, Nd: KLW) of dimensions up to 40mm× 40mm×5mm have been grown by top-seeded solution growth (TSSG) method. X-ray powder diffraction pattern was measured and compared with that of Nd: KLuW and Yb: KLuW. Absorption and fluorescence spectra were measured at room temperature. The Judd-Ofelt theory was applied to analyze the spectrum of Nd, Yb: KLuW crystal. The intensity parameters Ω t (t=2, 4 and 6) were calculated as Ω 2 =20.68×10 -20 cm 2 , Ω 4 =11.04×10 -20 cm 2 , Ω 6 =6.74×10 -20 cm 2 respectively, with a root mean square deviation of 0.58×10 -20 cm 2 .
