Growth and spectral properties of Er:Gd2SiO5 crystal

Abstract Er 3+ -doped Gd 2 SiO 5 (Er:GSO) single crystal with dimensions of ∅ 35×40 mm 3 has been grown by the Czochralski method. The absorption and fluorescence spectra of the Er:GSO crystal were measured at room temperature. The spectral parameters were calculated based on Judd–Ofelt theory, and the intensity parameters Ω 2 , Ω 4 and Ω 6 are obtained to be 6.168×10 −20 , 1.878×10 −20 , and 1.255×10 −20  cm 2 , respectively. The emission cross-section has been calculated by Fuechtbauer–Ladenbury formula.
