Activation of the Phoenix System

Fusion startup Xcimer Energy has activated the Phoenix laser system, which company representatives state is the largest privately owned laser in the world. The announcement was made on Wednesday.

The project is based on experiments conducted at the National Ignition Facility (NIF). In 2022, the NIF proved that a controlled fusion reaction could yield more energy than was consumed during the process.

Strategic Roadmap to Commercial Power

Company executives have identified the Phoenix system as the initial phase of a larger strategic objective. The company intends to use this prototype to move toward the construction of "Vulcan," which is planned to be the world's largest laser.

The ultimate goal for Xcimer Energy is the creation of "Athena," described by the company as the first commercial fusion power plant designed for continuous, grid-scale electricity generation.

Industrial Capabilities and Technical Recovery

According to the group, the process of designing, building, and operating Phoenix required Xcimer to rebuild specific industrial capabilities. Specifically, the company focused on large-scale electron-beam-pumped excimer lasers.

Company officials stated that this particular technical competence was in danger of disappearing following the Cold War.
