Three-dimensional display may be one of the most wonderful techniques attracting scientists to research on. But most of current approaches are fictitious ones. On the CLEO'94 , E. A. Downing and L. Hesselink et al. reported a virtual three-dimensional volumetric display using Pr doped fluoride glass upconversion luminescence which is evaluated as a new excellent physics achievement in 1996.The ZBLAN:Pr glass is proved by L. Hesselink to be a interesting material for three-dimensional volumetric display based on upconversion. In the processes of upconverting near-infrared radiation to visible, the 1G4 level of Pr locates at an important position. But the transition probability of 3H4-1G4 proved to be one or two order of magnitude smaller than other strong transitions. So to improve the population on 1G4 has an practical significance.In this paper, we report a simple 3-D volumetric display experiment which has used the upconversion sensitization *This project is supported by the National Natural Science Foundation of China 122 SPIE Vol. 3560 • 0277-786X198/$1O.00 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/26/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx

In this paycr we report the observation of multi-photon up-conversion luininescence phenomenon of ErPS014 noncrystalline induced by pulse DCAI dye laser and clarifjg that ihe mechanism of up-conversion is the step t).v step ahsorption of single E?+ ion.
