The ZT1 amorphous alloy film with a thickness of 70μm was ablated and cut in ultrafast laser (250fs). The study of ultrafastlaser removing morphologies and removing thresholds indicated thattwo distinctive ablation regimes including unmelted ablation and melted ablation existed in ZT1 amorphous alloy, depending on the incident laser fluence. The removing thresholds for these two ablation regimes were determined to be Fth1=0.17J/cm2, Fth2=2.15J/cm2, respectively. In cutting, the processing quality was closely related to the laser energy density. Andin the larger parameter range (2.2J/cm2<F0<12.8J/cm2), the cutting edge withoutcollateral damage could be obtained, which was closely related to the characteristics of laser Gaussian energy distribution and the threshold for material removal.
