Abstract

The expansion dynamic of the plasma produced by femtosecond laser ablation of different materials has been studied with a time resolved CCD camera in the UV-visible range. About 1 mj energy of a laser operating at 620nm issued from an amplified femtosecond CPM dye laser is focused (focusing diameter: 0.5 mm) onto a rotating target. The laser pulse width can be tuned from femtosecond to picosecond and nanosecond duration.
