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 the technical expertise of the local workforce. Home of the University of Arizona, Tucson has long been a center of specialty capacitor design and fabrication, offering Xcimer proximity to experienced suppliers, engineers, and technicians. Xcimer’s capacitor engineering and design team collectively brings decades of experience in the exact class of high-energy capacitors required for the world’s largest laser systems. Concentrating that expertise in a dedicated manufacturing environment will accelerate product development, improve quality control, and reduce program risk as the company prepares to complete it’s prototype Phoenix laser system in early 2026, and scales up to start construction of laser modules for Vulcan, the world’s largest and highest-energy laser which will achieve wall-plug breakeven from fusion for the first time.   “This facility gives us the space, the talent, and the manufacturing focus we need at exactly the right time,” said Xcimer Chief Operating Officer Brent
