Paper Abstract

The potential of pulsed laser system in the range of 10ps to 100ps pulse duration for material processing has been further investigated. In detail the dependency of the volume ablation rate, penetration depth and threshold fluence on the pulse duration and number of pulses applied to the material will be discussed. The experimental results show that in the case of copper and steel, better results in quality and efficiency of the ablated material are achieved with shorter pulse durations.
