飞秒脉冲烧蚀单晶硅的超快动力学
Ultrafast dynamics of intense femtosecond laser ablation of silicon
摘要
Abstract
The dynamic process of intense 50 fs laser ablation of silicon is investigated by the way of ultrafast time-resolved shadowgraph. The formation and development processes of plasma and shock wave are recorded, and it is known that the process of material ejection is discontinuous. The process can be divided obviously into two processes, which shows that at different stages there are different mechanism leading the interaction of laser and material. In the shadowgraph of 19 ns time delay, it is found that the shock wave is distorted from the hemispherical shape.关键词
