摘要
在已获得Ｔｍ３＋在Ｎａ５Ｔｍ（ＷＯ４）４晶体中强度参数Ωλ（λ＝２，４，６）的基础上，根据ＪｕｄｄＯｆｅｌｔ理论，计算了Ｔｍ３＋多重激发态之间的辐射跃迁几率、辐射寿命、荧光分支比及积分发射截面等光谱参数，并对晶体实现激光输出的可能性进行了讨论。
On the basis of the obtained intensity parameters Ω λ ( λ =2,4,6) of Tm 3+ in Na 5Tm(WO 4) 4 crystal, radiative transition rates, radiative lifetimes, branching ratios and integrated emission crosssection between the excited J manifolds of Tm 3+ were calculated and studied according to JuddOfelt theory. By using these spectral parameters, possibility of output of laser in crystals was discussed as well.
