Abstract: Spectral properties of Nd3+ ion in Sr3Gd2(BO3)4 crystal were investigated, where the crystal was grown successfully by the Czochralski method. The absorption spectrum in the range of 200-1000 nm was measured. The fluorescence spectrum and lifetime were determined excited with 808nm wavelength, and the emission cross-section was calculated. Based on the Judd-Ofelt theory the spectral parameters were obtained, which were compared with others Nd-doped crystals.

Key words: Nd3+:Sr3Gd2(BO3)4 crystal, optical properties, Judd-Ofelt theory
