摘　　要：用提拉法成功生长出Nd:Sr3Gd2(BO3)4晶体,并对其光谱性能进行了研究.测量了晶体在200～1000nm波段的吸收谱.用808nm的波长激发,测量了晶体的荧光光谱和荧光寿命,计算得到晶体的发射截面.根据J-O理论计算了晶体的光谱参数,与其它Nd掺杂的晶体的光谱参数做了比较和分析.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.
