We demonstrate a one-color one-beam pumping method for a three-dimensional two-step excitation fluorescent display with Er<sup>3+</sup> -doped ZBLAN glass. A localized green fluorescent spot is obtained by use of a focused pump-light beam at 979 nm. The quantum efficiency of the two-step excitation fluorescence is investigated in a time-dependent analysis and an experiment with a pulsed pump light.
