摘要：

The development of lasers in terms of pulse length and ablation quality has made wider the perspective of material processing. Ablation using picosecond lasers offers an almost "cold material removal", which causes minimal heat affected zones and enables sublimation without melt formation. Moreover, burst-mode intensifies these effects by the partition of pulses into groups of micro-pulses. Therefore, removal rate and surface quality are improved with an appropriate combination of burst-mode and other relevant process parameters. Nevertheless, parameter identification can be costly and time demanding. Thus, analysis of parameter impact offered by modern quality tools represents a convenient approach to accelerate ablation process improvements.
