    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.

  • USP Lasers Conquer Macroprocessing

    Press Release / 25.4.2019

    Dr. Arnold Gillner: The challenge is to get the photons to the workpiece.

    Ultrashort pulse (USP) lasers have become firmly established in science and micromachining. At this year's “UKP-Workshop: Ultrafast Laser Technology” in Aachen, a new trend has emerged: Macroprocessing. Since multi-100-watt USP lasers up into the kW range have become available, the industry is looking at them with great interest for large-area applications. For this purpose, the institute is developing the complete process chain right through to fully digitized processes.

    The Fraunhofer-Gesellschaft is launching a highly ambitious undertaking: the Fraunhofer Cluster of Excellence Advanced Photon Sources CAPS. The cluster aims to achieve international technological leadership in laser systems that reach maximum performance with ultrashort pulses (USP), as well as researching their potential applications, all in cooperation with Fraunhofer partners. The new systems are proposed to surpass all previous USP lasers by one order of magnitude in average laser power. At the same time, the partners are working on the required system technology as well as promising applications in industry and research.
