摘要

采用提拉法生长Nd3+掺杂浓度为1at%高质量的Nd∶Lu3Al5O12(Nd∶LuAG)晶体. 对晶体在不同气氛下退火的光谱性能进行了表征. 研究发现：256nm处的吸收峰是由Fe3+引起的;467和518nm处的吸收峰分别由O-心和F+心引起. 计算出809nm处的吸收截面为1.86×10-20cm2.利用JO理论拟合出Nd∶LuAG晶体的强度参数Ω2、Ω4和Ω6分别为0.71×10-20、1.13×10-20和4.36×10-20cm2;计算出Nd3+ 4F3/2能级到不同下能级的跃迁几率、荧光分支比、辐射寿命和发射截面等光谱参数,并对结果进行了相应的分析. 结果表明,Nd∶LuAG晶体是二极管抽运固态激光器中很有应用潜力的增益介质.

Abstract

High quality Nd∶Lu3Al5O12(Nd∶LuAG) crystal doped with 1at% Nd3+ was grown by the Czochralski method. The spectral properties of the crystal annealed in different atmosphere were characterized. The experiment indicates that the absorption band in 256nm, 467nm and 562nm are connected with Fe3+, O-, and F+, respectively. The absorption cross section at 809nm is 1.86×10-20 cm2. The spectral parameters are calculated by JuddOfelt theory, and the intensity parameters Ω2, Ω4 and Ω6 are estimated to be 0.71×10-20cm2, 1.13×10-20 cm2, and 4.36×10-20 cm2, respectively. The calculated radiative probabilities, branch ratios, radiative lifetime and emission cross section are evaluated for the 4F3/2 excited state by using the calculated intensity parameters. The results indicate that Nd∶LuAG crystal is a promising material for solidstate laser application.

Key words： Nd∶LuAG single crystal; absorption spectrum; J-O theory; fluorescence spectrum
