Clean energy by inertial fusion energy: A White Paper from Laseroptik

Inertial fusion energy holds promise as a clean, CO₂-free power source for the future. But making it a commercial reality depends on one thing: laser systems capable of delivering extreme power without compromising performance or reliability. This White Paper explores how advances in optical coatings—particularly through ion beam sputtering (IBS)—are addressing one of the field’s biggest challenges: producing durable, high-LIDT optics at scale.

High-power laser pulses are essential for initiating inertial confinement fusion, a breakthrough energy concept that mimics the process powering the sun. These laser systems rely on dielectric optics that can withstand intense pulses without damage. However, ensuring long component lifetimes under these extreme conditions requires next-generation manufacturing techniques and coating technologies.

In this White Paper, Laseroptik details state-of-the-art developments in IBS technology and explains how they are helping extend optic lifespan, increase laser-induced damage thresholds, and support the optical demands of tomorrow’s large-scale fusion research facilities.
