Shadowgraph of a shockwave after a femtosecond laser pulse coming from the right (see block arrow with “Laser”) has hit the material surface (left border). |
Empirical model of nanosecond-laser drilling: the process is characterized by two ablation tools, the laser beam itself (red arrow to the left, red curves) and the laser-induced plasma plume (right part and blue arrows). |
Experimental setup for femtosecond laser plasma investigations (ICCD = dicam pro). |
