Deutscher Zukunftspreis 2013

(PresseBox) (München, )
Mit ultrakurzen Laserpulsen lassen sich unterschiedlichste Werkstoffe schnell und präzise bearbeiten, ohne sie aufzuheizen. Mitarbeiter von Bosch, Trumpf, der Universität Jena und des Fraunhofer IOF haben Ultrakurzpulslaser zu einem erfolgreichen Werkzeug der Serienproduktion gemacht. Dafür haben sie am 4. Dezember 2013 den Deutschen Zukunftspreis erhalten.

Laser sind aus der industriellen Fertigung nicht mehr wegzudenken. Doch in bestimmten Bereichen stoßen konventionelle Systeme an Grenzen. Trifft ein Laserstrahl zum Beispiel auf Metall, erwärmt er es. Der Werkstoff schmilzt teilweise. Doch das Verhalten von geschmolzenem Material lässt sich nur schwer beherrschen. Es bilden sich Unebenheiten. Das Werkstück muss aufwändig nachbearbeitet werden. Das kostet Gljw fyh Gasg.
