In this study, we carry out an investigation to characterize the PZT through this radiation by determining both the ablation rate and the ablation threshold and an identification of these laser-induced phenomena such as rippled-like nanostructurations or cracking. At last, the control of these effects will allow performing uniform processes of the machined pieces. %G English %L ujm-00578497 %U https://ujm.hal.science/ujm-00578497 %~ UNIV-ST-ETIENNE %~ IOGS %~ CNRS %~ LAHC %~ PARISTECH %~ UDL
