| 摘 要： | 使用聚焦的800nm，120fs，200kHz的高频超短脉冲激光在Li20-Nb20s-SiO2系玻璃内部空间选择性析出了LiNbO3晶体．经一定条件的飞秒激光照射数秒钟后，玻璃内部激光会聚点的发光由原来的白色转变为强的蓝绿色．发光光谱测定表明，所产生韵蓝绿光为飞秒激光的倍频光．显微拉曼光谱测定表明，飞秒激光会聚处析出了LiNbO3晶体。

| Abstract: | Crystal of LiNbO3 was space-selectively induced in Li2O-Nb2O5-SiO2 glass by using a focused femtosecond laser with high repetition rate. The light, which emits from the focal point of the laser, turns from white light to green-blue one as the laser irradiates for a few seconds. The luminescence spectra of the emission from the focal point demonstrate that the green-blue light is the second harmonic generation of the incident femtosecond laser. Micro-Raman spectra demonstrate that LiNbO3 crystal is precipitated in the irradiated region of the glass. |
