摘要：

The spectral parameters of Er3+ in Yb3+/Er3+:KY(WO4)(2) crystal with space group C2/c have been investigated based on Judd-Ofelt theory. The spectral parameters were obtained: the intensity parameters Omega(lambda) are: Omega(2) = 6.33 x 10(-20) cm(2), Omega(4) = 1.35 x 10(-20) cm(2), Omega(6) = 1.90 x 10(-20) cm(2). The radiative lifetime and the fluorescence branch ratios were calculated. The emission cross section sigma(e) (at 1536 nm) is 2.0 x 10(-21) cm(2).
