Lawrence Livermore National Lab News
Laser Blazes New Milestone Toward Self-Sustaining Fusion Energy
LIVERMORE, Calif., Feb. 3, 2022 — Scientists at Lawrence Livermore National Laboratory’s National Ignition Facility (LLNL NIF) said that, for the first time, physicists have engineered and tested a laser system in which fusion itself — as opposed to external heating...
Biobased Method Could Extract Domestic Supply of Rare-Earth Elements
STATE COLLEGE, Pa., Oct. 26, 2021 — An eco-friendly way to extract and separate rare earth elements (REEs) from unconventional sources has been demonstrated by researchers at Penn State and Lawrence Livermore National Laboratory (LLNL). The method relies on a bacterial protein that is...
Optical Measurement Reduces Vibration in High-Power Lasers
BERKELEY, Calif., Aug. 2, 2021 — The Berkeley Lab Laser Accelerator (BELLA) Center at the U.S. Department of Energy’s Lawrence Livermore National Laboratory has developed and tested an optical system to precisely measure and control the position and pointing angle of...
Laser-Driven Semiconductor Switch Pushes Speed Capabilities of Next-Generation Communications
LIVERMORE, Calif., June 23, 2021 — A laser-driven semiconductor switch design can theoretically achieve speeds and voltages higher than existing photoconductive devices — potentially enabling communication speeds beyond 5G if the switch were to be miniaturized and incorporated...
Deep Learning Bolsters Laser-Driven Ion Acceleration Study
LIVERMORE, Calif., June 3, 2021 — Researchers at Lawrence Livermore National Laboratory (LLNL) have applied neural networks to the study of high-intensity short-pulse laser-plasma acceleration, specifically for ion acceleration from solid targets. In most instances, neural networks...
Image Recovery Method Improves Compressive Sensing, Phase Retrieval
LIVERMORE, Calif., Feb. 8, 2021 — Research from Lawrence Livermore National Laboratory (LLNL) has yielded a method of compressive image recovery that is trained on patches of images, rather than full-size images. The method, called GPP (generative patch prior), is able to recover a...
3D Printing Offers Versatility in Optical Design
LIVERMORE, Calif., Nov. 30, 2020 — Researchers at Lawrence Livermore National Laboratory (LLNL) used multimaterial 3D printing to develop tailored gradient refractive index glass optics, delivering a result that could enable the manufacture of improved military specialized eyewear...
Materials Expand Volumetric 3D Printing
LIVERMORE, Calif., Nov. 2, 2020 — A new class of materials adapted by researchers at Lawrence Livermore National Laboratory (LLNL) enable nearly instant production through volumetric 3D printing and expanding the range of material properties achievable with the technique. The...
LaserNetUS Awarded $18M by US DOE
WASHINGTON, D.C., Oct. 28, 2020 — The U.S. Department of Energy announced $18 million in funding for LaserNetUS, a network of 10 high-intensity laser facilities at national laboratories and universities in the United States and Canada. The initiative, established in 2018, is...
Optics: Form, Function and the Future
Oct 3, 2017 — For all of their diversity of form and function, the vast range of available optical components and optical fibers have much in common — materials, engineering and design, and techniques in fabrication and metrology. And they are among the...
Fine-Tuning Additive Manufacturing for High-Density Parts
LIVERMORE, Calif., June 17, 2014 — A new approach to selective laser melting (SLM) could alleviate long-standing challenges in additive manufacturing of high-density metal parts. Researchers at Lawrence Livermore National Laboratory and its Accelerated Certification of Additively...
Membrane Optics Telescope Demo’d for DARPA
BOULDER, Colo., Dec. 9, 2013 — A lightweight telescope created using polymer membrane optics and developed by Ball Aerospace & Technologies Corp. was demonstrated for DARPA, the company reported recently. Ball is incrementally demonstrating technology needed to deploy a...
NIF Fires Record-Setting Laser Shot
LIVERMORE, Calif., March 22, 2012 — The 192 lasers fired in unison at the National Ignition Facility this week delivered a record 1.875 million joules of ultraviolet laser light to its target chamber, exceeding NIF’s original design specification and setting the stage for...
Spin-Statistics Theorem Survives Test
BERKELEY, Calif., June 28, 2010 — The most rigorous trials yet of a fundamental assumption about how particles behave on the atomic scale has been conducted at the University of California at Berkeley. "We tested one of the major theoretical pillars of quantum field theory,...
