In the course of the Laser Optics Berlin trade fair, a research team of the Ferdinand-Braun-Institute (FBH) has been awarded the Transfer Prize WissensWerte on March 19, 2012. The FBH closely collaborated with JENOPTIK Diode Lab GmbH in Berlin-Adlershof on the prize-winning project on the development of high-power diode lasers for materials processing and, thus, ensured the rapid transfer of the research results into an industrial environment. The Transfer Prize is endowed with 50,000 euros and is assigned by the friends of the Technology Foundation Berlin (TSB).
The team led by physicist Dr. Götz Erbert is developing a novel generation of diode lasers for powerful laser systems used for materials processing. The diode lasers each with one single emitter currently deliver a typical output power of around 10 Watt. To enhance the performance of laser systems, it is not sufficient to simply increase the output power of the individual diode lasers. Instead, it is necessary to improve the effectiveness of transforming electrical into optical power and to optimize the beam quality of the single diode lasers forming such systems.
Based on novel designs, the FBH has now developed diode lasers with less energy loss than usual and without reducing beam quality either. The new diode lasers from the FBH achieve an efficiency of 63 percent at an output power of 12 Watt. 15 to 20 Watt shall be achieved while maintaining their efficiency and beam quality.
A long-term and intensive cooperation connects the FBH with the Jenoptik Group, particularly with JENOPTIK Diode Lab GmbH, founded in 2002. Jenoptik is currently expanding its plant for high-power semiconductor lasers at the Berlin-Adlershof location. The production capacities will more than double from 2013.
