摘要
本文应用Ｊｕｄｄ－Ｏｆｅｌｔ理论计算了Ｔｍ３＋离子在ＹＶＯ４晶体中的辐射跃迁几率ＡＪＪ′、无辐射跃迁几率ＷＪＪ′，振子强度ｆＪＪ′，荧光寿命τＪ，辐射跃迁截面σｅ和吸收截面σＡ等光谱特征参量．从速率方程得出在不同泵浦几率（１０２～１０５ｓ－１）下，荧光强度最大的掺杂浓度为４．５％～６．６ａｔ．％，并将这些结果与Ｔｍ３＋离子在ＹＡＧ晶体中的特征参量、最佳掺杂浓度进行了比较．
In the paper, the fluorescence characteristic paraneters of Tm 3+ ions in Tm 3+ ∶YVO 4 crystal for radiative transition probabiltites A JJ′ ,non-radiative transition probabilitics ω JJ′ ,oscillator strengths f JJ′ ,fluorescence lifetimes τ J,radiative transition cross sections σ e, and absorption cross sections σ A et. al. are calculated by use of Judd-Ofelt theory.From rate equations of populations of levels, the optioal doped concedtration X OP of Tm 3+ ions are calculeted as 4.5%～6.6% when range of probability of excited aevel by pump is 10 2～10 5s -1 under the circumstances fluorescence strength is maximum. These conclusions are compared with those of Tm 3+ ions in YAG crystals.
