Laser and Fiber Technology

For the development of high-power fiber lasers with diffraction-limited beam quality, Fraunhofer IOF has expertise in laser physics, fiber and optical design, glass chemistry, thermooptics, packaging and interconnection technology for fiber lasers, and the development of efficient fiber couplers and beam delivery systems.

Here, Fraunhofer IOF covers the entire technology chain in its fiber technology center, from the design and manufacture of laser-active preforms and fibers, preparation and characterization, to system integration of the laser-active special fibers and fiber-optic components. This is essential for the design and application of cw and pulsed fiber laser systems of the highest beam quality (M² < 1.2) with output powers up to the multi-kilowatt range. By operating technologies on an industrial scale, it is possible to quickly transfer new solutions into applications.

Fraunhofer IOF is one of the strongest research institutes with global visibility and numerous unique technological features.
