| Abstract: | Single crystals of Yb, Nd: KLu(WO4)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 Ωt (t=2, 4 and 6) were calculated as Ω2=20.68×10‐20cm2, Ω4=11.04×10‐20cm2, Ω6=6.74×10‐20cm2 respectively, with a root mean square deviation of 0.58×10‐20 cm2.
