The influence of average power, scanning speed, and repetition rate on the ablation rate and the width of heat affected zone is evaluated and discussed. Processing with a heat affected zone smaller than 5 µm and ablation rates of almost 100 mm3/min are achieved. Finally, precise cutting of 2 mm thick CFRP samples by repetitive ablation of a 350 µm groove with negligible heat affected zone is demonstrated.en621621journal article
