TechSpot: The world’s largest private laser just fired up in race to make fusion power real

The world’s largest private laser just fired up in race to make fusion power real

Prototype is an early step toward cheaper, laser-driven fusion energy

What just happened? The world’s largest privately owned laser has switched on in Denver, though it’s not part of a Bond villain’s plan to carve their name into the moon, sadly. Fusion startup Xcimer Energy has begun operations at Phoenix, a prototype system designed to test whether laser-driven fusion could one day produce commercial electricity.

Housed inside Xcimer‘s 74,000-square-foot laser facility, Phoenix uses a krypton fluoride excimer laser, a gas-laser design related to technology used in semiconductor manufacturing, albeit at a much larger scale.

The system’s light source operates at pulse energies of more than 1 kilojoule, while its core optical system includes a 38-meter-long gas optic used for stimulated Brillouin scattering pulse compression.
