摘要：

In this study, the effect of the laser process parameters on the quality of the drilled holes using Cu50Zr50 amorphous alloys foils is investigated experimentally. The results indicate that the diameter of the laser drilled micro-hole increases with the increase of the laser power or laser pulse width. The increasing speed decreases when the laser power or laser pulse width reaching thresholds of 120W or 1.1ms, respectively. The variation of diameter with the laser defocusing amount is not monotonic changing and dependent on both the laser defocusing amount and the laser power. The diameter of the laser drilled hole reaches a minimum value under the laser defocusing amount of -0.5mm for all the laser powers. The variation law of diameter with the laser defocusing amount is changing with the laser power. The formation mechanism of the laser drilled hole is analyzed based on the laser beam and the amorphous alloys foils properties.
