Lawrence Livermore National Laboratory News
National Ignition Facility Sets New Laser Energy Record
LIVERMORE, Calif., July 10, 2018 — Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) laser system has set a new record, firing 2.15 MJ of energy to its target chamber. This is a 15 percent improvement over NIF’s design specification of 1.8 MJ, and more than 10 percent higher than the previous 1.9-MJ energy record set in March 2012. This demonstration shot successfully meets a National Nuclear Security Administration (NNSA) Level 2 milestone for 2018. NIF, the world’s largest

LIVERMORE, Calif., March 13, 2015 — The world’s highest-peak-power laser diode arrays are now online at Lawrence Livermore National Laboratory. The 3.2-MW arrays are destined to become part of the High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) in 2017. Livermore has...
Light’s Wave-Particle Duality Visualized (with video)
LAUSANNE, Switzerland, March 3, 2015 — A novel imaging approach has brought light’s split personalities together for the first time. The wave-particle duality of light is well known, though experiments to date have only been able to observe one property at a time. But now a team of...
Image Correlation Helps Optimize Laser-Based 3-D Printing
LIVERMORE, Calif., Nov. 18, 2014 — Digital image correlation (DIC) analysis could help prevent warping of metal parts made via laser-based additive manufacturing. Researchers at Lawrence Livermore National Laboratory used the technique to find correlations between the power and speed...
National Energetics to Build 10 PW Research Laser
AUSTIN, Texas, Sept. 24, 2014 — A Consortium led by National Energetics Inc. has been awarded a more than $40 million contract to develop and install a petawatt laser system at a research facility being built outside Prague.
IR Method Detects Chemicals Remotely
PROVO, Utah, March 26, 2014 — Infrared technology could help the military to remotely and safely identify sites where nuclear weapons are being made. Researchers at Brigham Young University have developed a model that distinguishes the material in every pixel of an image taken...
Zygo Receives Support Order for Laser Fusion Amplifiers
MIDDLEFIELD, Conn., March 18, 2014— Zygo Corp. has been awarded a $1.4 million contract to produce meter-class laser fusion amplifiers for laboratory testing purposes.
Superbright X-Ray Free-Electron Lasers Find Missing Proteins
RICHLAND, Wash., and LIVERMORE, Calif., Feb. 21, 2014 — A protein's shape is key to understanding how it causes disease or toxicity. Traditionally, capturing quality x-ray snapshots of a protein has required as many as 1 billion copies of the same protein, stacked into a neat crystal. This is no longer...
Powerful Exoplanet Camera Unveiled
LA SERENA, Chile, Jan. 9, 2014 — After nearly a decade of development, a powerful exoplanet camera that detects IR radiation to image and analyze planets from other solar systems is now operational.
Spaghettilike surface makes stronger SERS sensor
ZURICH, and LIVERMORE, Calif. – Spaghettilike arrays of gold-coated metallic carbon nanotubes can amplify the signals of surface-enhanced Raman spectroscopy (SERS) enough to perform analyses that are more reliable, sensitive and cost-effective. Previously, the detection limit of...
Spaghetti-like Surface Makes Stronger SERS Sensor
ZURICH & LIVERMORE, Calif., Aug. 30, 2013 — An innovative plasmonic sensor amplifies the signals of surface-enhanced Raman spectroscopy (SERS) using a novel substrate based on carbon nanotubes with metal-coated tips. Scientists at ETH Zurich and the Lawrence Livermore National Laboratory...
After Fusion Failure, NIF Shifts Priorities
LIVERMORE, Calif., May 6, 2013 — Having failed to achieve fusion by its target date, the National Ignition Facility (NIF) is shifting its priorities and has replaced longtime director Dr. Edward Moses, Lawrence Livermore National Laboratory Director Parney Albright announced last...
Simulations Uncover Obstacle to Harnessing Laser-driven Fusion
COLUMBUS, Ohio, March 27, 2013 — A once-promising approach for using next-generation, ultra-intense lasers to help deliver commercially viable fusion energy has been brought into serious question by new experimental results and first-of-a-kind simulations of laser-plasma...
That’s No Moon: Deconstructing the Death Star
Dec 14, 2012 — In the original Star Wars movie Luke Skywalker, Han Solo and Obi-Wan Kenobi begin to ask thought-provoking questions about the amount of energy needed to vaporize an entire planet, and what sort of laser could achieve this. Maybe an hour into the...
