Abstract

The contours of the drilling-hole for the laser drilling at various inclination angles were investigated in this study. A simple model was proposed to estimate the drilling-hole shape and it was verified with experiments in pulsed laser drilling process. The contour dimensions of the drilling hole are significantly affected by laser power and inclination angle, and there is a good agreement between the simulation and measurement. Furthermore the laser induced plume on the graphite substrate heated by a Nd-YAG pulsed laser at various inclination angles was visualized experimentally. It can be found that the plume ejection is mainly normal to the substrate surface without the shielding gas.
