| 摘 要： | 用泵浦探测技术研究了掺杂CeO2的75TeO2-25Nb2O5-5ZnO玻璃在飞秒激光诱导的瞬态光栅多级自衍射。从拉曼和吸收光谱中研究了玻璃的结构特性，并证明了此玻璃中存在Ce3+离子。这种瞬态光栅起因于光克尔效应，并通过Ce3+离子中1S0?1F3电子能级跃迁形成的激发态粒子数光栅而改善，一级衍射信号的转换效率可达到11%。这些实验结果显示了掺杂CeO2的75TeO2-25Nb2O5-5ZnO飞玻璃在全转换开关中具有广泛应用。

| Abstract: | 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. |
