Nanospallation induced by an ultrashort laser pulse

A femtosecond laser pulse with power density of 10 13 to 10 14 W/cm 2 incident on a metal target causes ablation and ejection of the surface layer. The ejected laser plume has a complicated structure. At the leading front of the plume, there is a spall layer where the material is in a molten state....
