Xcimer is building the world’s biggest, brightest and most powerful lasers to commercialize the only scientifically validated form of fusion energy on Earth.
Co-authored by Xcimer founders and Dr. Dirk Sutter of TRUMPF Laser SE, white paper outlines why Xcimer’s approach offers potential for significant cost advantages.
We use the same approach as America’s National Ignition Facility – the only system in the world to demonstrate fusion ignition. We don’t need to spend time and money to demonstrate unproven plasma confinement physics; we combine NIF’s proven inertial confinement fusion approach with breakthrough laser technology. We’re driving down cost and complexity so we can deliver electricity on a pragmatic timeline and business model.
Approach
In early 2025, we completed the first private-sector electron-beam excimer laser – the first of its kind built by any organization in more than 20 years. In May 2025, our KrF laser set world records – and our groundbreaking hardware informs the design of our future systems at scale.
