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 Completes Crucial Experimental Shots at University of Rochester’s Laboratory for Laser Energetics

New data on hybrid hohlraums supports modeling, diagnostics, and path to scalable laser fusion systems The experiment is the latest in a growing body of Xcimer research that significantly derisks Xcimer’s approach to laser fusion – the only viable path to commercialize the only fusion approach that’s been scientifically validated to achieve net energy gain   DENVER, CO — MARCH 18, 2026 — Xcimer Energy today announced that it completed experimental shots at the University of Rochester’s Laboratory for Laser Energetics, accelerating the company’s goal of commercializing laser fusion. Scientists and engineers from Xcimer and partnering institutions conducted an experiment at the OMEGA Laser Facility as part of a National Laser Users’ Facility campaign. The experiment focused on externally driven halfraums (half-hohlraums) as part of early validation of Xcimer’s two-beam approach to inertial fusion energy. Scientists and engineers from Xcimer and partnering institutions conducted an experiment last month at the OMEGA Laser Facility as part of a National Laser Users’ Facility (NLUF) campaign. NLUF is a merit-based user program supported by the Department of Energy National Nuclear Security Administration, providing academic and industrial scientists and students with access to the world-class Omega Laser Facility for basic research. The experiment focused

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.

We’re scaling what works
  • 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.
