Abstract

High Power Lasers have been used for years in corresponding applications. Constantly new areas of application and new processes have been demonstrated, developed and transferred to fruitful use in industry and society. In the last years diode pumped solid state lasers in the multi-kW-power regime at beam qualities not far away from the diffraction limit have been developed. Consequently, a new area of applicability has opened. Many advancements can be realized even in classical applications like cutting (remote, 1µm-radiation), welding (high speed, remote), and surface treatment, however also new processes are established increasingly on that basis. Among others, the most important are 3-d metal build up in metal, ceramics and biocompatible polymers, selective laser melting, micro and nano-processing (ablation, structuring, polishing) and bio-photonic applications in diagnosis, microscopy and medical therapy. Remote contactless materials analysis by Laser induced breakdown spectroscopy LIBS allows new concepts and system in the recycling of metals and other raw materials.
