Focused Energy has announced plans to establish Sourcelight as an independent company, aiming to accelerate the industrial application of its laser-driven radiation source technology while continuing to focus on the development of laser fusion as its core business.
The move follows Focused Energy’s recent USD 240 million financing round and is intended to create a dedicated pathway for bringing laser-driven radiation source (LDRS) technology into industrial markets. The planned spin-off reflects the company's broader strategy of translating technologies developed through fusion research into practical industrial applications.
Sourcelight will focus on commercializing LDRS technology, which combines laser-driven high-energy X-rays and neutron sources within a single system. The technology is designed to support advanced imaging and material characterization capabilities, offering insights into both structural integrity and material composition.
For the non-destructive testing (NDT) sector, the technology presents opportunities in the inspection of safety-critical components, where conventional methods may face limitations related to penetration depth, resolution, material identification, or operational flexibility. Additional application areas identified by Focused Energy include nuclear waste characterization, industrial quality assurance, and security screening at container ports.
The technological foundations of the LDRS platform originate from research conducted by Focused Energy co-founder Prof. Markus Roth and collaborators on laser-driven particle acceleration. A significant step toward industrial deployment was initiated through the PLANET project, launched in 2024 and led by Focused Energy in collaboration with industry and research partners.
Explaining the rationale behind the spin-off, Thomas Forner, CEO and co-founder of Focused Energy, said:
"Focused Energy is pursuing the goal of making laser fusion industrially viable with full force. At the same time, technologies are emerging along this path that can generate tangible industrial impact at an earlier stage. Sourcelight is our way of clearly structuring and purposefully advancing this application perspective for laser-driven radiation sources."
Forner further highlighted the strategic importance of the company’s activities in Biblis, Germany, where both laser fusion and LDRS technology development efforts are underway.
"With Biblis—where we are also building the world’s first laser fusion power plant—we have a location with tremendous potential and visibility. It is also where the first industrial prototype of the LDRS technology is being developed. This will allow us to repeatedly demonstrate in Biblis how research can be translated into tangible industrial value creation, jobs, new technologies, and new companies. That is a strong message for Germany as a center of innovation."
According to the company, LDRS technology leverages high-power laser systems to generate compact sources of high-energy X-rays and fast neutrons. The approach enables non-destructive characterization of large components, sealed containers, and complex material structures without requiring physical access to internal features.
The technology's multimodal capability is considered one of its key differentiators. While X-rays provide information related to density and structural features, neutron-based imaging can reveal complementary details regarding material composition. Together, these capabilities offer enhanced analysis of complex and difficult-to-access objects.
Focused Energy noted that many comparable inspection and characterization techniques have traditionally relied on large-scale accelerator facilities or centralized research infrastructure, limiting their accessibility for industrial use. The company believes the LDRS platform could provide a more compact and flexible alternative for industrial inspection environments.
Discussing the commercialization strategy, Sebastian Wojczik, Vice President LDRS, said:
"Sourcelight is designed to turn technological innovation into industrial application. To achieve this, we are prioritizing concrete markets, validating use cases together with our partners, and building a platform that is scalable in the long term."
The planned launch of Sourcelight represents another example of advanced research generating technologies with potential applications beyond their original scientific objectives. As development progresses, the company aims to expand the adoption of laser-driven inspection and characterization technologies across industrial sectors where advanced non-destructive testing and material analysis capabilities are increasingly in demand.
