Science Award for Joint Laser Research Project under Participation of Jenoptik.

The project team consisting of 16 members from different institutes and companies won the “Stifterverband science prize” for the development of a platform for ultra-short laser pulses. Jenoptik’s Lasers & Material Processing division has been an impo
(PresseBox) (Jena, ) Together with partners from economy and science, the Fraunhofer Institute for Laser Technology ILT was awarded the “Stifterverband science prize” in Aachen on May 8, 2012. A new laser platform used to scale the power of ultra-short laser pulses received the prize during the Fraunhofer Annual Conference in Stuttgart. The pump source JOLD-650-HSF-4L in the form of a horizontal line had been provided for that development by Jenoptik’s Lasers & Material Processing division. It is capable of achieving a power density of over 16 watts per square millimeter. Compared to previously existing pump lines, the power has been doubled.
This result was both basis and motivation for the development of the femtosecond laser with high pulse power at the ILT.

High-power ultra-short laser pulses are ideal for precise and gentle application in medical engineering and material processing, e.g. for cutting glass. The laser platform newly developed by the ILT makes the high power of the ultra-short laser pulses possible by using the INNOSLAB amplifier as its core. Using that slab – a laser crystal plate – the developers were able to increase the average laser power of ultra-short pulse laser sources up to the range of several 100 watts.

The “Stifterverband science prize” awarded by the Stifterverband für die Deutsche Wissenschaft (Association for the Promotion of Sciences and Human-Centred Technology in Germany) carries a value of 50,000 Euros and honours scientifically excellent joint research projects between Fraunhofer institutes, the commerce and other research institutes. In the case of this joint research project of the ILT, the excellent interdisciplinary cooperation across locations was particularly recognised. RWTH Aachen University, the Max Planck Institute of Quantum Optics as well as the companies Amphos and EdgeWave have been among the current project partners of the Fraunhofer ILT in addition to Jenoptik’s Lasers & Material Processing division.

Awarded Projects with Jenoptik’s Participation.

Another project involving high-efficiency diode lasers Jenoptik participated in got an award only in March. In cooperation with the Lasers & Material Processing division, the Ferdinand Braun Institute, Leibniz Institute for Ultra-High Frequency Technology (FBH) had developed new diode lasers at its premises in Berlin. Those lasers lose significantly less energy than usual without that deteriorating the beam quality. The joint research project was awarded the Transfer Prize 2012 for the quick transfer of research to industrial application.
