Lawrence Livermore
Research Company/Group
For more than 60 years, the Lawrence Livermore National Laboratory has applied science and technology to make the world a safer place.
Livermore’s defining responsibility is ensuring the safety, security and reliability of the nation’s nuclear deterrent. Yet LLNL’s mission is broader than stockpile stewardship, as dangers ranging from nuclear proliferation and terrorism to energy shortages and climate change threaten national security and global stability. The Laboratory’s science and engineering are being applied to achieve breakthroughs for counterterrorism and nonproliferation, defense and intelligence, energy and environmental security. Source

With thousands of lasers packed into Livermore’s one-square-mile footprint, personnel working in laser facilities must be familiar with the procedures for safely operating and servicing laser systems. Even though laser light is in the non-ionizing part of the electromagnetic spectrum, it can cause injury and permanent damage in the blink of an eye. This dangerous potential of laser light came to a head after a near-miss incident in 2024.
Meet LLNL Interns: Jennie Ren, NIF&PS Graduate Scholar

Research Sheds New Light on Laser Polarization Effects in NIF Experiments
By Patricia Brady,,(925) 423-4332 Experiments at LLNL's National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a 3-millimeter hole at the top or bottom of a 2-centimeter gold canister known as a hohlraum. As they enter, the beams intersect in plasma and transfer power, a process known as crossed-beam energy transfer (CBET).
National Ignition Facility & Photon Science
The National Ignition Facility (NIF) is the world’s most energetic laser, operated by Lawrence Livermore National Laboratory for the Department of Energy’s National Nuclear Security Administration. NIF achieves fusion ignition in a lab to secure and modernize the nation’s nuclear stockpile. It starts in the control room, where operators configure thousands of parameters on NIF’s 192 lasers, all of which will fire onto a small object called a target.

LLNL Hosts Laser Safety Officer Workshop
Laser safety officers and health and safety professionals gathered at LLNL recently for a Department of Energy (DOE) workshop to exchange insights, strengthen best practices, and discuss their evolving challenges and responsibilities. The 2026 DOE Laser Safety Officer (LSO) Workshop, held May 19 to May 21, provided a valuable forum for collaboration, professional development, and shared commitment to laser safety across DOE operations.
DSSI Class of 2025
Meet the Data Science Summer Institute class of 2025. Students tackled a shared problem in computer vision for laboratory automation: Students explored the use of computer vision techniques on synthetic data to train models that will be applicable to automated laboratory tasks. In an automated laboratory, computer vision models drive components such as sensors and robotic arms, enabling experiments to be completed without exposing scientists to hazardous tasks.
LLNL's "AI in Eight Pages" team on the Startup Tri-Valley podcast
Cindy Gonzales, Brian Giera, and Caspar Donnison of Lawrence Livermore National Laboratory joined host Yolanda Fintschenko on the Startup Tri-Valley podcast to discuss their landmark AI report and why it matters far beyond the tech world. The conversation covers AI literacy, model limitations, workforce impacts, and policymaking, with a clear throughline: AI is not a magic wand, and understanding its risks is just as important as recognizing its promise.
Open data, shared impact
In data science, progress depends on access, not just to tools and talent, but to meaningful data. At Lawrence Livermore National Laboratory, the Data Science Institute’s Open Data Initiative, or ODI, is helping expand that access by making select LLNL datasets publicly available to the broader scientific community.
Yeping Hu to present at EMI Conference in June
Lawrence Livermore’s Yeping Hu will present research on surrogate modeling at this year’s Engineering Mechanics Institute (EMI) Conference, held June 2–5 in Boulder, Colorado. A researcher in the Laboratory’s Computational Engineering Division, Hu works primarily in the AI4Science domain, specializing in machine-learning (ML) solutions for manufacturing processes.
