Abstract :
Ultrashort laser sources with pulse durations of around a few or below 1 picosecond and average powers above 1 KW enable a new domain in precision machining. They enable extreme-precision cutting, ablation and drilling of even weakly absorbing materials, multi-component and multilayer systems.
