Modern ultrafast laser systems often allow for socalled burst-mode operation. This means that trains of ultrashort pulses are emitted with intra-burst repetition rates in the MHz- or GHz-range. These operation modes offer new possibilities in micromachining of different materials such as milling, drilling, or cutting. In this article, we give a short overview of recent developments and cite some achievements in micromachining applications of different materials in these new burst-regimes.
