%X Multiple order self-diffractions by femtosecond laser-induced transient grating in CeO2 doped 75TeO2-25Nb2O5-5ZnO glass are investigated by pump-probe technique. The glass structure and component are investigated by Raman and visible--NIR absorption spectra. It is showed that there exists Ce3+ ion in tellurite glass, and the transient grating is created by the optical Kerr effects and improved by the excited particle grating from the resonant absorption of the 1S0to 1F3 electronic energy transition of Ce3+ ion, and the conversion efficiency of the first order diffraction signal reaches about 11%. The results indicate that CeO2 doped 75TeO2-25Nb2O5-5ZnO glass has potential applications in ultra-fast all-optical switching.
