Abstract

Laser ablation presents a promising technique for material processing. The quality of products is strongly influenced by the properties of the laser-induced plume. In compressible flow, the ambient conditions can be transmitted upstream. Therefore, the laser ablation process is strongly affected by the ambient conditions. In this paper, the effects of laser intensity, back pressure and temperature on the laser-induced plume were studied using a numerical model, which calculates the density, pressure and temperature of the laser-induced plume at different laser intensity and ambient conditions. The results are in agreement with experimental results available in the literature and can be used for the optimization of the pulsed laser deposition process.
