Its success hinges on powering high-energy, ultra-precise solid-state lasers. Nestled in Charlotte, North Carolina, Northrop Grumman’s SYNOPTICS ® has been a trusted leader in growing synthetic laser crystals for over six decades. From the Mars Rover to premier medical laser systems, innovators have relied on SYNOPTICS around the globe for large-scale in-house crystal growth, fabrication, thin film coatings and component assembly capabilities. The team’s most recent achievement will help power the future of fusion. Northrop Grumman SYNOPTICS grew and harvested a ytterbium-doped yttrium lithium fluoride (Yb:YLF) crystal boule, with a diameter three times bigger than the industry standard. Laser crystals, like Yb:YLF, are the heart of solid-state laser systems. They serve as gain media or the core material inside a laser that amplifies light required to produce a laser beam. Demanding applications, like inertial confinement fusion, require high-energy laser systems which in turn require large crystal boules. This achievement is more than a material science feat – it’s a gamechanger for fusion research. Parts from this crystal will go on to power high-energy laser systems for inertial fusion energy research at Germany’s renowned research center, Deutsches Elektronen-Synchrotron (DESY). This SYNOPTICS’ crystal will power the laser systems needed to unlock fusion’s potential as a clean energy source, putting humanity one step closer to harnessing star-like energy on Earth. Inertial confinement fusion creates energy with zero greenhouse gas emissions and minimal waste. Dr. Kevin Stevens, general manager at Northrop Grumman SYNOPTICS, recognizes its potential to provide a clean and safe source of energy. “We’ve just grown one of the largest and purest crystals of its kind, a landmark moment,” Stevens said. “This achievement opens new possibilities for our customer’s laser system design, bringing us one step closer to unlocking clean, limitless energy that could transform how we power our world and fuel innovation for generations to come.” With the launch of Inertial Fusion Energy Laser Development and HED Analytics, (IFuEL), a broad multi-institutional Fusion 2040 consortium including DESY and funded by the German Federal Ministry of Research, Technology, and Space (BMFTR), DESY is advancing a new generation of laser technology for inertial fusion energy. The project targets one of the central challenges in fusion laser development: achieving high wall-plug efficiency in scalable, reliable, high-energy laser systems. Building on more than a decade of cryogenic Yb:YLF laser research in DESY, IFuEL will develop a 200-Joule-class laser module as a potential building block for future fusion laser drivers. This progress is enabled by record-size, high-quality Yb:YLF crystals grown by Northrop Grumman’s SYNOPTICS, whose large aperture and high optical quality are essential for efficient high-energy, high-average-power laser operation. Explore how Northrop Grumman SYNOPTICS helps laser engineers power their next breakthrough with premier laser materials. The knowledge gained from the completion of this project will help push the boundaries of other boule growth efforts.
