When lasers cross: LLNL finds a brighter way to measure plasma
Measuring conditions in volatile clouds of superheated gases known as plasmas are central to pursuing greater scientific understanding of how stars, nuclear detonations and fusion energy work. For decades, scientists have relied on a technique called Thomson scattering, which uses a single laser beam to scatter from plasma waves as a way to measure critical information…

Enabling an enabling technology
With the ability to print metal structures with complex shapes and unique mechanical properties, metal additive manufacturing (AM) could be revolutionary. However, without a better understanding of how metal AM structures behave as they are 3D printed, the technology remains too unreliable for widespread adoption in manufacturing and part quality remains a challenge…
Big Ideas Lab podcast delves into advanced lasers
It’s been laughingly said that “LLNL” stands for “lasers, lasers and nothing but lasers.” For physicists Tom Spinka and Jackson Williams, it can certainly feel that way. “Lawrence Livermore National Laboratory is world-renowned as one of the places to be, if not the place to be, for lasers,” Spinka said. LLNL’s best-known laser system is the National Ignition Facility (NIF…
