Abstract
Despite the invention and availability of a wide variety of laser sources, only very few types have made their way into the industrial use, which very often requires reliable three shift running, high uptime and low running costs. Over a long time the CO2 gas laser has dominated the high power material processing area and still holds with 41.1 % the biggest market share in that field. The most modern, most reliable and most cost efficient type of CO2 laser is the diffusion cooled slab configuration, which provides almost diffraction limited beam quality and is nowadays available in a power range up to 8 kW. The advantage of solid state lasers is that their radiation can be guided through optical fibers, but they suffered from high cost and low efficiency. The appearance of diode lasers as a very efficient and reliable pumping source, however, has boosted solid state laser technology. Not only the beam quality and efficiency of the classical rod design could be improved by replacing broadband lamps by monochromatic diode lasers but furthermore, because of the high brilliance of the diode lasers, new concepts as the thin disc and the fiber laser could be realized. Especially the higher efficiency, reducing the running cost in conjunction with improved beam quality makes the solid state lasers the tool of the future, whenever 3D applications are under consideration.
