Abstract

The structuring of functional and design metallic surfaces takes full advantage of economic, flexible and fully automated processing techniques. Structuring by laser remelting enables totally new possibilities for structuring with individual textures without any ablation of material or the utilization of harmful chemical etching. The functional principle requires the superposition of three laser beams emitted from two different laser sources. For this process, a new optical system is designed and built up which allows for the combination of cw and pulsed laser beams on a working plain. To maintain a high degree of flexibility and automation the system allows for a high number of degrees of freedom for each individual beam. To take full advantage of structuring by remelting for the processing of 3D surfaces, the optical system needs to be extended. With additional optical capabilities elliptical pre-shaping can be applied to enable robust and reliable processing. The huge amount of degrees of freedom leads to a challenging, complex optical design that is being discussed in this work.
