Nd~(3+) doped KLa(MoO_4)_2 single crystal was grown by the Czochralski method. The nonpolarized absorption and fluorescence emission spectra were investigated at room temperature. The FWHM of the absorption peak at 805 nm is 10 nm, and the absorption cross-section is 3.74×10~(-20) cm~2. The fluorescence lifetime of the main emission peak at 1 059.45 nm is 160.6 μs. The J-O intensity parameters were calculated by the Judd-Ofelt theory, and some other parameters such as spontaneous radiative transition probabilities, the branching ratios, radiative lifetime, fluorescence quantum efficiency and stimulated emission cross-section as well.
