研制了Gd2O3摩尔分数可达30%、掺Ce3+的SiO2-B2O3-Al2O3-Gd2O3系统、高密度闪烁玻璃。研究了用BaO和La2O3取代Al2O3时玻璃的吸收光谱和荧光光谱等性能的变化，发现BaO在摩尔分数为10%时有着最佳的荧光性能，同时BaO或La2O3取代量的增加会使得激发谱和发射谱的峰值波长红移。在X射线激发下，该玻璃表现出闪烁性能，闪烁发光的中心波长比330 nm波长紫外光激发下的荧光中心波长红移了40 nm，显示了闪烁发光与荧光发光有着不同的发光机理。

选择中频电磁感应加热提拉法生长出了透明、基本无散射和气泡、无包裹物的高质量的铥(Tm)取代钇（Y）的原子数分数为2%的Tm:YLiF4（YLF），并采用X射线衍射（XRD）法对晶体进行了物相分析。测试TmYLF晶体的吸收光谱并计算了Tm离子对不同波长的吸收系数和吸收截面。同时测定其荧光光谱并分析了3H4－3F4和3F4－3H6跃迁产生的发射峰。对TmYLF晶体进行了激光实验，当输入功率为160 W时，获得了54.4 W的激光输出，斜率效率为35.6%，最大光光转换效率为31.2％。

基于体光栅的耦合波理论,推导了飞秒脉冲通过无吸收、透射型体光栅时衍射光强的频谱表达式和瞬时表达式。在此基础上,讨论了二者随折射率调制度的变化。发现在一定的折射率调制度范围内,衍射脉冲的瞬时变化为:开始是单脉冲,然后中心向下凹陷分裂为二个脉冲,而后是三个脉冲。如果此时折射率调制度进一步增加,则脉冲数目又回复到一个脉冲。在一定的折射率调制度范围内,上述过程是重复发生的。同时发现,在折射率调制度处于1.0×10-3-1.0×10-2区间时,双脉冲间隔随折射率调制度增大而增大。对衍射光强谱随折射率调制度的变化进行了数值模拟,并对衍射脉冲的瞬时变化进行了解释。

LiLuF₄ single crystals co-doped with thulium (5%) and holmium (0.5%), having large size, intact shape, and high optical quality, are successfully grown by the Czochralski technique. Absorption and fluorescence spectra of the crystal are measured. The absorption spectrum shows that the main absorption band locates at near 686 and 792 nm and the °uorescence spectrum peaks at 2.05 \mu m. At room temperature, the as-grown Tm, Ho: LiLuF₄ single crystals are end-pumped by a fiber-coupled laser diode system with pumping wavelength of 795 nm under CW operations. A power of 50 mw continuous laser output at 2.05 \mu m wavelength is achieved. Meanwhile an obvious green light is detected.

The Yb:YAG and Yb:YAP crystals have been grown by Czochralski method. The absorption spectra and the fluorescence spectra of Yb:YAG and Yb:YAP crystals have been investigated. It is shown that the Yb:YAG crystal has better laser properties and smaller threshold power than Yb:YAP crystal. In addition, the absorption cross-section of the Yb:YAP crystal is 2.16 times of that of the Yb:YAG crystal, so laser diode pumped Yb:YAG lasing can be easily realized. Because YAP single crystal is anisotropic, it is provided with polarization characteristics.
