Abstract
Laser-induced forward transfer (LIFT) technique is available for the fabrication of micro-sized thin film. In this paper, the LIFT process of gold film was investigated by the microscopic two-dimensional laser induced fluorescence (2D-LIF). The dynamic behavior of the gold atoms and emissive particles were observed in vacuum and atmospheric air. Characteristic behavior was observed for different species. The atoms flew with the fastest speed of more than 2 km/s. The influence of ablation laser energy, film thickness, and the presence of the the substrate on the dynamics of the species are reported.
