Abstract

AbstractLaser beam micro joining is known as one of the most promising applications of laser technology. The paper will give an overview of new applications in microtechnology using laser beams with high beam quality such as fiber lasers. Hence two new processes will be reported. The combination of small focus dimensions with high feed rates for scanning has advantages for metal welding as well as for polymer welding. Advanced Microsystems with complicated welding contours especially from the medical and biotechnological applications are challenging the limits of laser welding of polymers.
