摘　　要：Nd3＋： Li3Ba2La3（MoO4）8 crystal has been grown from a flux of Li2MoO4 by the top seeded solution growth method （TSSG） and its structure was confirmed by X-ray diffraction. The polarized absorption spectra, fluorescence spectra and fluorescence decay curve of the crystal were measured. The main spectral parameters were calculated by the Judd-Ofelt theory and compared with other Nd-doped crystals. The broad absorption bands and the large absorption cross sections around 805 nm indicate that the crystal is very suitable for diode-laser pumping. The broad emission bands around 1060 nm show that the crystal is a potential medium for tunable and short pulse lasers. The quantum efficiency of the crystal is up to 95%, which is higher than the value for Nd3＋：YVO4 and Nd3＋：YAG and comparable to that of other disordered molybdate crystals. The excellent spectroscopic properties show that Nd3＋：Li3Ba2La3（MoO4）8 crystal may be regarded as a potential solid state laser host material for diode laser pumping.Nd3＋： Li3Ba2La3（MoO4）8 crystal has been grown from a flux of Li2MoO4 by the top seeded solution growth method （TSSG） and its structure was confirmed by X-ray diffraction.
