摘要

The unique properties of ultrafast laser pulses pave the way to numerous novel applications. Particularly lasers in the sub-picosecond regime, i.e. femtosecond lasers, arrived at a level of reliability suitable for the industrial enviroment in the last decade and now gain an increasing recognition since such pulse durations combine the advantages of precise ablation with higher efficiency especially in the case of processing metals. However, for some micro processing applications the infrared wavelength of these lasers is still a limiting factor. Thus, to further broaden the range of possible applications, there is a need for industrial femtosecond lasers with shorter wavelengths. To that extend, we present results obtained with a frequency doubled TruMicro 5000 FemtoEdition. We show that, depending on the processed material, the higher photon energy as well as tighter focusing options of the shorter wavelength can open up a new regime of processing parameters. This regime is not accessible by infrared light, leading to a wider range of possible applications.
