Surface Structuring with Ultra-short Laser Pulses: Basics, Limitations and Needs for High Throughput
TL;DR: In this article, it is shown that the ablation process itself shows a maximum efficiency at an optimum fluence, and the corresponding removal rate directly scales with the average power and depends on the threshold fluence and the energy penetration depth into the material.
