Abstract

A high-power short-pulsed Nd:YAG laser was focused onto carbon steel targets with a 13-mum-thick Zn coating. The ablation effects, the behavior and the characteristics of the laser-induced products were studied. The ablationrate was defined as the ablated volume divided by consumed laser energy, and nas used as a description of ablation cleaning ability. The dependence of ablation rate on laser fluence was plotted, and the optimum processing conditions were determined. The laser induced products consisted of plasma-vapor and Liquid particles. The length of the laser-induced plasma-vapor was approximately 2 cm and its existence time wavered at approximately 4 mus. It was observed that the moving direction of the liquid particles was in a small angular range that was tilted toward but symmetric to the incident laser. It was further noticed in this range that a higher moving velocity was obtained when the angle between the liquid particles and the incident laserbeam was larger. The estimated highest moving:velocity of the liquid particles was approximately 0.8 m/s. The analysis of the condensed particles confirmed that the laser-induced product on the target surface consisted of Znand Fe, which mainly solidified from plasma-vapor and melt, respectively.
