Inside the National Ignition Facility, 192 laser beams push the limits of science and technology, supporting critical national security and scientific research. But the extreme energy takes a toll, leaving tiny cracks and damage on the system’s delicate optics.

Instead of replacing these costly components, scientists at Lawrence Livermore National Laboratory have developed a high-tech repair process: the Optics Recycle Loop. Like a Formula 1 pit stop for lasers, this system inspects, restores, and reintegrates damaged optics with precision—keeping NIF firing at peak performance.

In this episode, we explore how researchers extend the life of these vital components, the cutting-edge science behind laser damage repair, and why maintaining NIF’s optics is key to its success.
