Time-resolved investigations of plasma and melt ejections in metals by pump-probe shadowgrpahy

Article

Abstract

Ablation of bulk metals (Al, Cu) has been investigated in situ by means of high-resolution pump-probe photography using pump laser radiation of pulse duration tp=80 fs, at wavelength of 820 nm.

Depending on material-specific parameters, qualitatively different ablation phenomena have been observed. Structural analysis by electron and optical microscopies reveals rosette-like surface structures showing the morphology of the ablated regions. The temporal development of the ablation dynamics can be conditionally categorized into different characteristic time regions. Particularly, laser induced melt injection has been observed in the time range of 700 ns to 1.1 μs after the initial laser-metal interaction.
