| 中文摘要 | 用提拉法成功地生长了6mol％的高浓度掺铒铌酸锂晶体。测量了晶体的两个非偏振方向（X和Z）以及两个偏振方向（π和δ）的吸收光谱。高浓度掺铒铌酸锂晶体的吸收系数高，有利于提高泵浦效率。根据所测的吸收光谱用Judd-Ofelt理论拟合出了Er^3＋离子的强度参数Ωλ。所得的均方差结果显示偏振拟合的误差要小于非偏振拟合。利用偏振吸收数据计算了各能级跃迁的自发辐射跃迁几率（AJJ’）、辐射寿命（τ）、荧光分支比（β）和积分发射截面（σp）等参数，对计算结果进行了讨论并与其他文献的报道结果进行了比较。; A highly doped Er3+ : LiNbO3 (concentration 6 mol%) crystal was grown successfully by Czochralski method. The absorption coefficient of the grown crystal is higher than that of the lowly doped E3+ in LiNbO3 crystal, which is helpful to improve the pumping efficiency. The absorption spectra at two unpolarized directions (X and Z) and two polarized directions (E parallel to Z, E perpendicular to Z) were measured. Using the Judd-Ofelt theory, and according to the measured absorption spectra, the intensity parameters Omega(lambda) of Er3+ were fitted. The results of root-mean square (r. m. s) deviation show that the error of polarized fitting is less than that of unpolarized one. Thus fluorescence transition probabilities (A(JJ')), radioactive lifetime (tau), fluorescence branching ratio (beta), and integrated emission cross section (sigma(p)) were calculated and accepted according to the polarized results, and were also discussed and compared with the ones reported in the literature. |
