Time-resolved shadowgraphs and holograms of intense femtosecond laser ablation of aluminum are reported. The different bending trends of interference fringes are found in the ablations of aluminum and other materials at probe wavelengths of 400 and 800 nm, for the first time to our knowledge, which could be attributed to the ejection of massive neutral droplets induced by critical-point phase separation during the second material ejection.
时间分辨阴影图和全息图报道了高强度飞秒激光烧蚀铝的情况。我们首次发现,在探测波长为 400nm 和 800nm 时,铝和其他材料的烧蚀中干涉条纹的不同弯曲趋势,这可以归因于在第二次材料喷射过程中由于临界点相分离而引起的大量中性液滴的喷射。
