Accelerating the shift to abundant energy.

Xcimer is building the world’s biggest, brightest and most powerful lasers to commercialize the only scientifically validated form of fusion energy on Earth.

Xcimer Energy delivers technical update to U.S. Energy Sec. Chris Wright and U.S. Rep. Gabe Evans in Denver laser bay

High-level visit, also including Chancellor of Colorado State University System Dr. Tony Frank, comes after Xcimer begins testing of one of the highest-energy KrF lasers in the world Xcimer’s prototype laser system, code-named “Phoenix,” will be complete in 2026; project is on-schedule and on-budget The leading laser fusion company has also advanced its multistate site search to house Vulcan – a high-yield laser fusion facility expected to demonstrate engineering breakeven in 2031   DENVER, Colo. (Dec. 23, 2025) – Xcimer Energy Inc. welcomed U.S. Energy Sec. Chris Wright and U.S. Rep. Gabe Evans of Colorado to the company’s Denver laser bay on Monday for a technology briefing and update on its progress to commercialize laser fusion. Earlier this year, Xcimer completed the first key component of its prototype laser system. Just last week, the company began testing the highest-energy KrF laser built in the 21st century. This laser provides the optical energy to power the “Phoenix” pulse compression prototype, which generates laser pulses with the optical characteristics needed to ignite inertial fusion fuel capsules.  Xcimer’s Phoenix system will be fully complete in H1 2026, Xcimer Energy Co-founder and CEO Conner Galloway said. Phoenix is on-schedule and on-budget, Galloway said in

OUR APPROACH

We’re scaling what works

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

  • OUR ACHIEVEMENTS

    Validating and Advancing Commercialization

    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.
