摘要：

The spectral parameters of Nd3+ ions in Nd:KLa(WO4)(2) crystal have been investigated based on Judd-Ofelt theory. The spectral parameters were obtained: the parameters of oscillator strengths Omegalambda are Omega(2)=3.0887x10(-20) cm(2), Omega(4)=1.0375x10(-20) cm(2), Omega(6)= 1.0422x10(-20) cm(2), the radiative lifetime is 685 mus, the quantum efficiency is 30.7%, and the fluorescence branch ratios were calculated: beta(1)=0.432, beta(2)=0.475, beta(3)=0.089, beta(4)=0.004.
