研究了两束激光作用下的上转换三维(3D)立体显示，所用材料为ZBLANPr，Yb氟化物玻璃。所用的两束激光是波长分别为960 nm（半导体激光器）和820 nm（Ti宝石激光器）。对Pr3+离子双频上转换发光进行了研究，分析了上转换发光强度与抽运光强度和离子掺杂浓度的关系，从而得出了实现较清晰双频上转换3D立体图像的实验条件。ZBLAN玻璃为双频上转换3D立体显示的基质材料，主要由于其有非常好的声子光谱声子频率小于580 cm-1；当激光强度很小时，上转换荧光强度将随着两抽运激光强度的增加而线性增加；ZBLAN玻璃中Pr3+离子和Yb3+离子的最佳掺杂摩尔分数为0.5%和1.5%。

Two beams of pumping up-conversion three-dimensional (3D) volumetric display which is based on a ZBLANPr, Yb fluoride glass are investigated. The lasers employed are infrared semiconductor laser with wavelength 960 nm and tunable Ti gem laser with wavelength of 820 nm, respectively. The two frequency up-conversion luminescence of Pr3+ ion is investigated. The relation between up-conversion fluorescence intensity, pumping lasers intensity, and ion doped concentration is analyzed, and the experimental conditions to realize the clear two frequency up-conversion 3D display are therefore obtained. ZBLAN glass is selected as two-frequency up-conversion 3D volumetric display foundation material for it has perfect phonon spectrum whose maximum phonon frequency is 580 cm-1; up-conversion fluorescence intensity increases linearly with augment of two beams of pumping lasers intensity when lasers intensity are very weak; optimal doped concentration of Pr3+ and Yb3+ ions are 0.5% and 1.5% mole fraction, respectively.
