Laser-driven fusion. Engineered for commercial power from day one.
We are pursuing a laser-driven inertial fusion approach - built to unlock fusion energy’s full potential.
December 2022: the National Ignition Facility (NIF) in the U.S. proved laser fusion can achieve net energy gain. But NIF answered a scientific question, not a commercial one.
Marvel Fusion is on the mission to close that gap.
Marvel Fusion’s Technology Approach: Hollow Shell Fast Ignition
This includes:
- A high-repitition laser platform.
- Nanostructured targets with non-cryogenic fuel, built for scalable manufacturing.
- A fuel cycle that steadily reduces reliance on tritium.
Three building blocks. Each reinforces the others. Together: a credible path to commercial fusion energy.
Efficient and scalable laser drivers
Built around efficient, high-repetition drivers, leveraging mature industrial supply chains, with a clear path to higher performance and lower cost.
DPSSL
The baseline platform
Diode-pumped solid-state laser (DPSSL) technology: wall-plug efficiency above 10%, high repetition rates, long operational lifetime, mature industrial supply chain. A proven, credible path to deployment.
We're demonstrating this through ATLAS at Colorado State University, Fort Collins. Infrastructure completes in 2026.
First laser commissions in 2027, validating:
- ~200 J pulse energy, short-pulse operation
- 100 fs pulse duration
- Up to 10 Hz repetition rate
- Wall-plug efficiency above 10%
- Automated target handling, integrated radiation protection
From 2028: the emphasis shifts from proof to scale - beam energies exceeding 2 kJ at European XFEL, Hamburg.
Next-generation laser
Alongside DPSSL, we're developing a new laser architecture - targeting a lower cost per delivered kilojoule, with far greater flexibility in pulse duration and shaping.
- Advanced laser tech demo: 2027
- Sub-scale kilojoule-class system: from 2028
Commercial deployment doesn't depend on it. DPSSL is a complete, independent path to ignition. This next-generation laser is our upside - on economics and fuel flexibility.
Power plant integration
Developed jointly with Siemens Energy from day one. Our power plant integrates the fusion core, energy conversion, fuel cycle, and grid connection into one system.
Lower tritium requirements mean simpler fuel handling, licensing, and maintenance - and a simpler plant. Future neutron-source facilities will validate shielding and plant interfaces along the way.
The result: a clear route to a standardized, replicable blueprint for tomorrow's power plants.
One Mission, three revenue streams
Our mission: commercially competitive fusion power plants. Every laser, every target, every facility serves that goal.
But unlike most deep-tech ventures, we don't wait for the first plant to create value. The same technologies that enable fusion also stand on their own as products - generating revenue, and retiring risk, long before ignition.
Industrial Laser Systems
The DPSSL platform, built for fusion, also serves scientific research, semiconductor manufacturing, industrial processing, and defense — commercialized through Caelora, our laser business. Early revenue. Real-world validation. A supply chain our fusion facilities will depend on. Every improvement feeds straight back into the fusion roadmap.
Neutron Sources
Run below ignition conditions, our HSFI targets produce intense-pulsed neutrons — no full power plant required. A low-capex entry point serving materials qualification, semiconductor reliability, isotope production, and nuclear research.
Not a detour: the same lasers, targets, and facilities that ignition requires. As laser energy and target performance scale up, the neutron source evolves naturally into a demonstration of target gain (Q_target > 1) — the lowest-capex, lowest-complexity path to high-gain fusion in the industry. Along the way, it funds development and retires the technical risk of the ignition facility that follows.
Fusion Energy Infrastructure
Grid-connected power plants delivering reliable, abundant, carbon-free baseload electricity — built on our validated laser platform, target architecture, and neutron-source experience. Developed with Siemens Energy. The goal: not one demonstration plant, but a standardized platform for global deployment.
Each stream de-risks and finances the next. What's traditionally a binary technology bet becomes a sequence of independently valuable milestones, capital invested today captures value at each one, long before the first plant switches on.
