Abstract

The present study is focused on determination of the ablated volume and profile of lines, by femtosecond laser dynamic scanning process. After identification of the laser-matter interaction parameters (w0 - waste size, α−1 - optical penetration depth, Fth - fluence threshold for one pulse) with static shots, experimental and calculated line volume and profiles will be compared. An analytical model of prediction of the metal ablation volume is proposed taking into account the material properties, the laser beam characteristics and the dynamic scanning parameters.
