Paper Abstract

Incoherent superpositioning of radiation from a single-mode fiber bundle with 200 mW output power per fiber allows to realize power densities of 2 MW/cm2. The total power being directly scalable with the number of fibers. With special optics for imaging the fiber-bundle endface onto the target instead of simply focusing it is possible to control the power density within that spot. Coherent superpositioning allows to further increase the power density and to direct the beam to a spot within the field of the incoherent superposition. Such systems could be useful for all kinds of applications requiring high-brightness radiation like cutting and welding or laser projection, printing plates, lithography, etc.
