Liao is one of 107…

Two LLNL researchers named to Optica’s 2024 class of senior members

Lawrence Livermore National Laboratory (LLNL) researchers Paul Armstrong and Brent Stuart have been named senior members of Optica. The professional society’s senior membership status recognizes members with more than 10 years of professional experience in optics or an optics-related field. The 2024 class joins a distinguished group of scientists, engineers, entrepreneurs…

Research confirms importance of symmetry in pre-ignition fusion experiments

Researchers at Lawrence Livermore National Laboratory (LLNL) have retrospectively confirmed that implosion asymmetry was a major aspect for fusion experiments before achieving ignition for the first time at the Lab’s National Ignition Facility (NIF), the world’s most energetic laser. The findings were recently detailed in a Nature Communications paper titled “The impact of…

LLNL’s Tammy Ma shares fusion energy vision with TED

What would you do with the largest laser in the world? That’s the question Lawrence Livermore National Laboratory (LLNL) physicist Tammy Ma posed to the audience on the mainstage at the influential TED conference held in April in Vancouver. In the talk, which was publicly released today, Ma shared her answer: bringing about a world powered by laser-based fusion energy,…

LLNL researchers uncover key to resolving long-standing ICF hohlraum drive deficit

A team of researchers at Lawrence Livermore National Laboratory (LLNL) has made advancements in understanding and resolving the long-standing "drive-deficit" problem in indirect-drive inertial confinement fusion (ICF) experiments. This discovery could pave the way for more accurate predictions and improved performance in fusion experiments at the National Ignition Facility…
