摘要：
The spectroscopic characteristics of Er3+/Yb3+: LiLa(WO4)(2) crystal were investigated. Based on the Judd-Ofelt theory, the following intensity parameters Omega(lambda) were obtained: Omega(2) = 9.03 x 10(-20) cm(2), Omega(4) = 2.02 x 10(-20) cm(2) and Omega(6) = 0.59 x 10(-20) cm(2). The upconversion emission of Er3+/Yb3+:LiLa(WO4)(2) crystal was investigated under excitation with the 976 nm diode laser. The Er3+/Yb3+: LiLa(WO4)(2) crystal has the intensity parameters Omega(lambda) and a strong emission of 562 nm wavelength. Er3+/Yb3+: LiLa(WO4)(2) crystal may be regarded as an upconversion laser material for the green light.
