【摘要】：正飞秒激光作用在材料表面造成形态学变化,可以大大改变材料的物理性质。但目前已有的研究还未能获得激光作用时完整的物质形态响应过程。针对该问题,美国罗切斯特大学郭春雷教授的研究团队开发了一种超快光学成像技术。该项技术利用散射光,可以得到近零背景、高对比度的高质量真实空间图像,从而展示飞秒激光作用金属时形态表面结构动力学演变的全过程。在飞秒激
[Abstract]:Due to the effect of positive femtosecond laser on the surface morphology of the material, the physical properties of the material can be greatly changed. However, the existing studies have not been able to obtain the complete response process of material morphology. In response to this problem, the team of Professor Guo Chunlei at the University of Rochester developed a super-fast optical imaging technique. By using the scattering light, a high quality real space image with near zero background and high contrast can be obtained, thus showing the whole process of the dynamic evolution of the morphology surface structure when the femtosecond laser acts on the metal. In femtosecond excitation
