Abstract

Ultrafast lasers appear very promising for material removal with ultra high precision because ablation is expected to be "cold" and not affected by plasma interaction in that case. It turned out, however, that the mere reduction of pulse duration does not guarantee the absence of recast and beam deformation. This contribution will present some progress in fundamental understanding of the ultrafast ablation process opening the way to develop technical means allowing to achieve an unprecedented level of accuracy at acceptable expenses and to choose optimal beam parameters, e.g. the pulse duration for which an optimum was found in the short picosecond range.
