Abstract

采用固相反应和真空烧结技术制备了掺杂浓度为1.0at%的Nd:YAG透明陶瓷样品,并测试了样品的吸收光谱和荧光光谱.样品在主吸收峰808nm处的吸收截面为3.10×10^-20cm^2,主荧光发射峰位于1064nm处,实测荧光寿命为257μs.应用Judd-Ofelt理论计算了Nd^3+在YAG中的强度参数Ωλ(λ=2,4,6)、跃迁的振子强度、自发辐射跃迁几率、辐射寿命、荧光分支比等光谱参数.最后计算得到Nd:YAG透明陶瓷中Nd^3+:^4F3/2→^4I11/2跃迁对应的受激发射截面大小为3.81×10^-19cm^2.结果表明。Nd:YAG透明陶瓷具有较大的受激发射截面和高的荧光量子效率(接近100%),是一种性能优良的激光材料.
