Optical System Alignment, Tolerancing, and Verification XI.
High-precision laser micro machining gains more importance in industrial applications every month. Optical systems like the helical optics offer highest quality together with controllable and adjustable drilling geometry, thus as taper angle, aspect

The use of a helicaloptics to drill micro holes in fuel injectors and spinning nozzles has already demonstrated great advantages likehigh precision and flexibility. Due to the laser beam rotation on a helical path, the hole-geometry is almost indepen

We present a new method for the creation of hierarchical structures by two subsequent steps of laser ablation. To create certain functionalization of surfaces hierarchical structures are often required. These structures can be considered as a microst

In this paper an ablation cutting process of thin Si wafers with an ultra-short pulsed laser system (5 ps) is investigated in order to optimize specific process parameters. In contrast to state-of-the-art technologies like blade sawing and nanosecond

The increasing use of plastics as a construction material has given rise to the problem of how to join dissimilar materials. For the production of hybrid plastic-metal components, several processes are possible. In a new joining method LIFTECA (R), r
