Ytterbium doped potassium lanthanum tungstate crystal [Yb:Kla(WO4)2, abbreviated Yb:KLW] was grown by the Czochralski method. The infrared spectra and Raman spectra of the crystal were measured and the vibrational mode was assigned.The lattice parameters of the crystal obtained by X-ray diffraction are a=b=0.532 nm and c=1.189 nm and the melting point determined by thermogravimetry-differential thermal analysis is 1 119 ℃. There is no phase transition below the melting point. The absorption spectrum and fluorescence spectrum of the crystal were measured, and the corresponding spectral parameters were calculated.The results show that there are stronger and broader absorption peaks at 931 and 981 nm, and an emission wavelength of 1 021 nm for the crystal. It is suitable for use in InGaAs laser diode pumps as the excitation source.
