The name Fraunhofer has always been associated with the application of future-oriented technologies. The job opportunities and career prospects for those interested in taking on challenging tasks where science and industry meet are as diverse as the research areas of the Fraunhofer Institutes.

A current employer ranking by employer branding consultancy Universum, which WirtschaftsWoche Online has now published online, shows that publicly funded employers are currently popular among students. More than 50,000 students were asked which employer they would most like to work for after graduation. Following the Max Planck Society in first place and Bayer in second place, the respondents voted the Fraunhofer-Gesellschaft into third place, followed by Tesla (fourth) and the German Aerospace Center DLR (fifth). The European Space Agency ESA reached position 8 in the survey.

Photonic components and systems for quantum technology

News / May 2021

Photonics is a key for novel applications based on quantum technology – for quantum computers, quantum internet or quantum metrology, among others. Together with top German and international researchers, Fraunhofer ILT scientists are developing a broad portfolio of solutions for new quantum technologies. In addition to lasers and fiber technology, these include parametric photon sources and frequency converters as well as integrated optical components and packaging processes.

News at a Glance


USP lasers revolutionize battery and hydrogen technology

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.

Intelligent robots for targeted combating of viruses and bacteria

Service robots can help ensure that buildings and means of transport are cleaned and disinfected regularly and with consistently high quality. Since October 2020, twelve institutions of the Fraunhofer-Gesellschaft have been working on the development of new technologies for this field of application. Led by Fraunhofer IPA, the partners are pooling their expertise in the “Mobile Disinfection" (MobDi) research project to contribute to a safe “New Normal” in times of pandemic. The project is part of the »Fraunhofer vs. Corona« action program.

EHLA Tuning: Roller Coating at up to 200 Meters per Minute

The Fraunhofer Institute for Laser Technology ILT's globally successful EHLA extreme high-speed laser material deposition process is not only turning heads. In the collaborative project EVEREST, the institute – along with three industrial partners – has developed process and system technology to efficiently repair and coat components and tested it on rollers. Now after successfully completing the project, the Aachen researchers want to establish the newly developed process chain in the industry. The goal is to coat long and large rollers and other rotating components with the EHLA process in a near-net-shape, both reliably and extremely efficiently.
