Xcimer activates largest privately owned laser, Phoenix, for fusion energy supply chain push

Xcimer Energy turned on Phoenix, a 38-meter krypton-fluoride excimer laser generating over 1 kilojoule, the largest privately owned laser in the world. The system uses electron-beam-pumped excimer technology, demonstrating Stimulated Brillouin Scattering pulse compression at record energy levels. Phoenix targets a commercial reactor needing over 12 megajoules, aiming to outperform NIF's solid-state design with lower cost and faster shot rates.
