An investigation of piezoelectric cutting by femtosecond laser

The cutting of the piezoelectric ceramic Pb(ZrxTi1-x)O3 (PZT) with femtosecond lasers for high technology applications allows better results compared to nowadays techniques, but have revealed several undesired behaviours, although this techniques seems well suited for more common materials. 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
