  • Abstract
    In this paper, we show that selective crater morphology, top-hat to Gaussian-like ~ 10 mum crater, can be obtained with an ultrafast laser system without any additional spatial shaping system (as a consequence, without any supplementary cost and complexity), only by varying the applied intensity on the material. The experiments are performed in single shot regime and for two pulse durations (7 and 28 fs experiments).
