High precision and high throughput material processing using ultrashort pulsed laser radiation of high average power requires a detailed understanding of the laser matter interaction on ultrafast time scales. In this paper, we will focus on energy transport mechanisms based on the two-temperature-model and the resulting ablation regimes for single pulses. Heat accumulation at high pulse repetition rates and spatial pulse overlap will be discussed. Additional, a novel nonthermal ablation mechanism for graphite and corresponding materials will be presented.
