ResumoAbstractThe spectroscopic characteristics of Er3+/Yb3+:LiLa(WO4)2 crystal were investigated. Based on the Judd–Ofelt theory, the following intensity parameters Ωλ were obtained: Ω2=9˙03 × 10–20 cm2, Ω4=2˙02 × 10–20 cm2 and Ω6=0˙59 × 10–20 cm2. 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 Ωλ 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.Keywords: JUDD–OFELT THEORYER3+/YB3+:LILA(WO4)2 CRYSTALUPCONVERSION EMISSION
