IPG Laser GmbH, a subsidiary of IPG Photonics Corporation, announced that it installed a diode-pumped 20 kilowatt Ytterbium fiber laser system, the world's most powerful commercial solid-state laser in Berlin under a contract award from BAM (Bundesanstalt für Materialforschung und–prüfung/the German Federal Institute for Materials Research & Testing).

BAM, the national materials and chemicals technological institute of Germany, purchased a YLR-20000 with central emission wavelength of 1070nm and beam quality of less than 11 mm x mrad. The unit is water cooled and delivers 20kW of output power through a flexible fiber having a 200µm core. The efficiency, beam quality and the size of the 20kW fiber laser are without match by any other solid state laser in the world. It will be used for materials processing research on alloys and steel.

"The installation at BAM signals that IPG is opening doors to new challenges in materials processing", stated Dr. Valentin Gapontsev, CEO of IPG Photonics Corporation. "In addition to a 36kW laser and another 20kW laser ordered previously by Japanese and US customers, BAM's purchase of a 20kW laser proves that IPG is setting commercial records in addition to laboratory records for our advanced technology." Dr. Gapontsev added "there is great interest in our higher power systems because they are enabling new applications that other laser technologies cannot."

Prof. Dr. Thomas Böllinghaus, Vice President of BAM, stated "BAM welcomes partners in industry and science for cooperation with BAM in all high power applications."

IPG sells cost-effective CW Ytterbium fiber laser systems from 1W to 50kW for a variety of materials processing applications in different industries. With several worldwide production facilities, IPG has the capacity to meet volume requirements for its high power lasers. IPG's diode-pumped fiber lasers offer performance, maintenance, reliability, and cost advantages over conventional solid state and gas laser systems.
