The world’s largest privately owned laser just turned on
Xcimer’s approach to fusion power is modeled after the National Ignition Facility (NIF), which proved in December 2022 that a controlled fusion reaction could release more power than required to ignite it.
The NIF trained 192 laser beams on a fuel target smaller than a pencil eraser. The energy from the lasers hit the gold target. As the lasers obliterate the gold target, their energy is converted into X-rays, which are focused on the fuel pellet inside, compressing it until atoms in the fuel fuse and release energy.
