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.

New peer-reviewed measurements overturn decades-old assumptions and enable a next-generation fusion laser design Researchers at Xcimer, University of Illinois and University of Alberta demonstrated high-resolution, absolute measurements that confirm textbook models omit key behavior The breakthrough on Stimulated Brillouin Scattering confirms a key feature of Xcimer’s laser fusion architecture, which is more than an order […]

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 […]

TUCSON, Ariz. (Dec. 4, 2025) – Xcimer Energy Inc. is expanding its U.S. manufacturing operations in a Tucson industrial facility, where the leading laser fusion energy company will scale up production of components for its high-energy lasers, including high-performance energy storage capacitors.  The decision to expand in Tucson reflects the region’s longstanding capacitor industry and […]

  Xcimer will hire 13 summer interns for the 12-week program, with smaller cohorts in spring and fall.  All positions are paid and include housing and relocation stipends for those who live outside the Denver area. The internships are part of a bigger staffing push at Xcimer, which recently expanded its leadership team, hired sector […]

Xcimer’s next-generation facility, Vulcan, will deliver the world’s highest laser energy and house the largest laser amplifiers ever built. Led by Brian Boggs, this effort will bring high-skill jobs and anchor the next wave of U.S. clean-energy innovation.

Denver-based inertial fusion company’s electron-beam excimer laser is also the first of its kind built by any organization in more than 20 years; in May, it achieved the longest pulse length of any KrF laser.   Xcimer Energy announced today the completion and operation of the world’s first electron-beam-pumped excimer laser built in the private […]

As Xcimer accelerates hiring, we’re proud to welcome Dr. Silvia De Dea—who helped build some of the most complex machines humans have ever created—as our new Head of Materials and Process Engineering. Alongside this key hire, we’re launching a world-class Science and Technology Advisory Board, bringing together top experts in fusion, engineering, and laser science to help advance Xcimer’s mission and explore adjacent markets.

Xcimer Energy Inc. announced that it has completed the first key component of its prototype laser system, Phoenix, currently under development at its Denver facility. The newly completed Long Pulse Kinetics (LPK) platform is an electron-beam pumped excimer laser created to validate Xcimer’s modeling and design of such systems.  Xcimer’s fusion approach, which experts recognize […]
