Fraunhofer Institute for Laser Technology ILT, along with economy and science partners, has won the ‘Stifterverband science prize’ in Aachen on May 8, 2012.
The prize was presented at the Fraunhofer Annual Conference in Stuttgart, to a new laser platform that can scale the power of ultra-short laser pulses. The horizontal line pump source JOLD-650-HSF-4L offered by Jenoptik’s Lasers & Material Processing division, supported the development. A power density of over 16 W/mm2 can be achieved using that powerful source. It has power twice as much as the already existing pump lines. Based on this high-power achievement, femtosecond laser with high pulse power was developed at the ILT.
Ultra-short laser pulses with high-power can be effectively used for cutting glass and suitable for tender and highly-accurate application in material processing as well as in medical engineering. By deploying INNOSLAB amplifier as its core, ILT’s laser platform can achieve high power of the ultra-short laser pulses. The designers used a laser crystal plate to enhance the average laser power of ultra-short pulse laser sources up to the range of some 100 W.
Stifterverband für die Deutsche Wissenschaft’s Stifterverband science prize recognizes scientifically excellent joint research projects between Fraunhofer institutes, the commerce and various other research institutes and honors them with 50,000 €. Besides the Jenoptik’s Lasers & Material Processing division, the Fraunhofer ILT’s current project partners include the Max Planck Institute of Quantum Optics, RWTH Aachen University, Amphos and EdgeWave.
Jenoptik participated in another award-winning project, wherein high-efficiency diode lasers were included. Based on the capability to quickly transfer research to industrial application, the joint research project was awarded the Transfer Prize 2012, during March.
