| 中文摘要 | 采用波长800 nm、脉冲宽度120 fs的飞秒激光对温度梯度（TGT）生长的Ti宝石进行辐照后，材料呈暗黑色。通过相关数学模型计算出Ti宝石在激光辐照瞬间的热影响范围(HAZ)为1.968n * 10~(-3) mum，材料最高温度达1.47 * 10~5 K。样品经飞秒激光辐照后吸收增大，但没有新吸收峰出现，通过对比不同品质因数（FOM）值的Ti宝石样品在420 nm处荧光谱发现，飞秒激光辐射后420 nm处荧光度强度增大是由于样品中Ti~(4+)浓度增大引起的。拉曼光谱和X射线衍射（XRD）的检测结 |
| 英文摘要 | Ti-doped sapphire turned dark irradiated by a 120 fs pulse laser with 800 nm wavelength. Heat af-fected zone(HAZ) and the highest temperature of irradiated zone are 1.968 * 10~(-3) mum and 1.47 * 10~5 K re-spectively by calculation calculated. There is no new absorption peaks appeared in absorption spectra after femtosecond laser irradiation. According the relation between figure of merit(FOM) of crystals and fluores-cence intensity at 420 nm, fluorescence intensity increase means that Ti~(3+) in the crystals changed to Ti~(4+) during femtosceond laser Irradiation. Results of Raman spectrum and XRD indicate that lattice distorted and quality of lattice declined after irradiation. |
