Laser Fusion as a Spillover Effect: How Research Is Already Leading to Industrial Applications Today
June 18, 2026
Laser-driven fusion is considered one of the great technological hopes for the energy supply of the future. As a field of the future with nationwide significance, an innovation ecosystem is currently emerging around fusion technology, whose impact extends far beyond Bavaria and is already making its mark. In particular, the high-power lasers developed for this purpose are already opening up new applications in other markets, such as material characterization. In this interview, Sebastian Wojczik, Vice President of Laser-driven Radiation Sources (LDRS) at Focused Energy, explains how laser fusion generates industrial spillover effects and why SourceLight plays a central role in this process.
Sebastian, fusion is a key application for your lasers. With your SourceLight application platform, you’re demonstrating that the technology goes far beyond that. What other areas of application do you see, and where are concrete use cases currently emerging?
Laser fusion remains Focused Energy’s core business. At the same time, the development of laser fusion is yielding technological building blocks that may become relevant in industrial applications sooner than expected. We aim to apply LDRS (Laser-Driven Radiation Sources) technology to non-destructive testing and material characterization. We see concrete use cases primarily in areas where today’s testing and analysis methods reach their limits: in the characterization and qualification of radioactive waste, in security and customs inspections, in industrial quality assurance, and in safety-critical components and complex material structures.
What can be inferred from your example regarding Germany as a deep tech hub? Should potential secondary applications be considered earlier and more systematically?
Yes, but with discipline. Deep tech projects often give rise to technological capabilities that extend beyond the original use case. These spin-off applications should be identified early on, but not pursued indiscriminately. From our perspective, this requires a clear transfer strategy: The core focus remains unchanged—in our case, laser fusion at Focused Energy. At the same time, selected technological building blocks are evaluated based on specific customer problems, market requirements, and industrial feasibility.
How can we identify such spillover effects more effectively without diluting the original technological focus?
You have to consider both sides simultaneously: the technology and the market. Clear governance is essential. Spillover effects should be prioritized based on defined criteria: technical fit, market demand, regulatory feasibility, access to pilot customers, and commercial scalability. This preserves the original focus while still ensuring a systematic approach to the transfer.
What are the biggest hurdles for such deep-tech spillovers: technical maturity, regulation, financing, market access, or the trust of potential users?
All of the points mentioned are relevant. The most difficult part is usually not the idea itself, but the transition from a scientifically sound approach to a robust, economically viable, and regulatory-compliant system.
For LDRS, technical maturity, system integration, and reliability are key challenges. Added to these are radiation protection, permits, safety requirements, and integration into existing industrial processes. Especially in regulated markets, technological superiority alone is not enough. Users must gain confidence in performance, operational safety, traceability, and long-term maintainability. Financing is also critical, because deep-tech hardware involves longer development cycles and higher initial investments than pure software development. That’s why strong partners, clear milestones, and early industrial validation are crucial.
Where does the technology currently stand on the path to industrial application, and when do you expect the first practical applications, such as in safety inspections or materials testing?
The technology is transitioning from scientific and technical development to industrial validation. An important reference point is the PLANET project, in which a prototype for a laser-driven neutron source for industrial applications is being developed in collaboration with partners from industry and research at the site of the former Biblis nuclear power plant. For the first practical applications, it is crucial that not only the radiation source functions properly, but the entire system as well: the laser, targets, detection, data analysis, radiation protection, operational concept, and integration into real-world workflows. We are therefore not talking about a short-term mass-produced product, but rather about step-by-step further development in specific application areas. Initial controlled demonstrations and pilot applications are the next logical step on the path to industrial use.
What role do partners, networks, and industrial users play in turning a technological opportunity into a marketable product?
A crucial role. In deep tech, a marketable product isn’t created in the lab alone. Industrial users help define real-world requirements. Partners from industry and research are equally important for components, system integration, security, data analysis, and scaling. Networks and collaborations in research and development can help bring together the right users, technology partners, and funding structures early on.
How do you assess Bavaria’s potential as a location for your project?
Fundamentally, we see very relevant points of connection in Bavaria: a strong industrial base, expertise in mechanical engineering, automation, photonics, security technology, energy infrastructure, and rigorous quality assurance.
Especially for the industrialization of LDRS technology, it is important to have an environment where technology development, industrial application, and scaling are closely integrated. In our view, Bavaria offers a very interesting ecosystem for this.
