Résumé

Ablation characteristics of piezoceramics PZT have been investigated through femtosecond laser irradiation (120fs, 800nm, 5kHz, 0.2mJ) for industrial applications. First experiments demonstrate that unexpected features such as melting, microcracks, spallations or redeposition can damage the quality of the process and the performances of the final product. This work intends to quantify the ablation rate, the ablation threshold and the incubation phenomena to upgrade the quality of the industrial process. Optimizations based on ablation efficiency and visible nanostructurations are proposed.
