ResumoThis paper reports the growth, structure and optical characterization of a new laser crystals Nd3+:Li3Ba2Gd3(WO4)8. Li3Ba2Gd3(WO4)8 compound crystallizes in the monoclinic system with space group C2/c, and cell unit parameters: a = 5.217(3) Å, b = 12.763(9) Å, c = 19.204(13) Å, β = 91.928(17)° and Z = 2. Nd3+:Li3Ba2Gd3(WO4)8 crystals have been grown by TSSG method. The spectroscopic characterization of Nd3+:Li3Ba2Gd3(WO4)8 crystals was investigated. In comparison with the other Nd3+-doped tungstate crystals, Nd3+:Li3Ba2Gd3(WO4)8 crystal has broad absorption band, large absorption cross-section and value of σemτ. The results regard Nd3+:Li3Ba2Gd3(WO4)8 crystal as a potential solid-state laser material for diode laser pumping.
