    Ultrafast lasers have become a standard manufacturing tool for the display industry, with even more and even larger applications coming in the next few years. The technology and processes needed for these new applications were presented at the 6th “UKP-Workshop: Ultrafast Laser Technology”, held by the Fraunhofer Institute for Laser Technology ILT in Aachen on April 21 and 22, 2021. Their spectrum ranged from ultra-powerful beam sources to processes that can be used to enlarge the surface of a metal electrode, for the generation of hydrogen, a thousand times.

    The development of the world's most precise clock is the ambitious goal of the “Thorium Nuclear Clock” project, in which Fraunhofer-CAPS scientist Dr. Johannes Weitenberg is involved. Conventional atomic clocks on the effect of the characteristic frequency of radiation transitions in the electron shell. The Thorium Nuclear Clock, on the other hand, uses effects in the atomic nucleus.
