Bringing new life to Laser Guide Star

Earlier this year, Lawrence Livermore engineering technical associate Pam Danforth applied 30 years of laser experience to an out-of-this-world problem -- bringing new life to the University of California's Lick Observatory Laser Guide Star.The Lick Observatory's Laser Guide Star is vital to astronomers because a natural guide star isn't always near an object they want to…

Laser researchers revolutionize aviation industry

Editor's note: This article is part of an occasional series about LLNL entrepreneurs.Most people don't realize it, but the airplane they are flying on may be stronger and safer thanks to a pair of former Lawrence Livermore National Laboratory researchers who developed and commercialized an innovative but relatively obscure technology.Lloyd Hackel and Brent Dane found a way…

NIF experiments show initial gain in fusion fuel

LIVERMORE, Calif. - Ignition -- the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel -- has long been considered the "holy grail" of inertial confinement fusion science. A key step along the path to ignition is to have "fuel gains" greater than unity, where the energy generated through fusion reactions exceeds the…

New X-ray analysis method opens the door to researching an elusive class of proteins

An international team of researchers has demonstrated a new method for studying the structure of proteins that could lead to important advances in biology and other fields. For the first time, protein crystals have been studied in two dimensions at room temperature with X-rays, using a new technique that could open the door for scientists to learn more about an important…

NIF experimental campaign highlighted by Physical Review Letters

Demonstrating the controlled fusing of deuterium and tritium (hydrogen isotopes), such that more energy is produced than is used to create the fusions, is one of the stated goals of the National Ignition Facility (NIF). Two papers published Feb. 5 in Physical Review Letters describe the "high-foot" series of experiments begun last spring, which bring NIF closer to…

Lawrence Livermore scientist selected as SPIE Fellow

LIVERMORE, Calif. - Lawrence Livermore National Laboratory (LLNL) scientist Steve Payne was recently selected as a fellow of SPIE, an international professional society for optics and photonics. Payne, an active SPIE participant since the mid-1980s, is the group leader for sensor materials and measurements in the Lab's Materials Sciences Division and is the associate…

Journal cover features Lawrence Livermore's intense laser interaction simulation research

Research from the Lab'sFrederic Perez, Andreas Kemp, Laurent Divol, Cliff Chen and Prav Patel is featured on the cover of the Dec. 13 2013 issue of Physical Review Letters. For several decades, physicists have used lasers of very high power, such as at LLNL's Jupiter Laser Facility, to create extreme states of matter. By focusing such lasers to a beam as narrow as a few…

WHO: Lawrence Livermore National Laboratory (LLNL) and Femtolasers will announce a new partnership.WHAT: Following an international competitive tender, LLNL will announce Femtolasers as the winning bidder for supply of a cutting-edge short pulse front-end, which will seed the High Repetition Rate Advanced Petawatt Laser system (HAPLS), currently under development for the…

Lawrence Livermore researchers demonstrate high-energy betatron X-rays

A Lawrence Livermore team, along with researchers from the University of California at Los Angeles and SLAC National Accelerator Laboratory, has recently produced some of the highest energy betatron X-rays ever demonstrated, with the added benefit of being produced on a system the size of a large tabletop. Betatron X-ray radiation, produced when relativistic electrons are…

Laser fusion experiment yields record energy at LLNL's National Ignition Facility

LIVERMORE, Calif. -- In the early morning hours of Aug.13, Lawrence Livermore's National Ignition Facility (NIF) focused all 192 of its ultra-powerful laser beams on a tiny deuterium-tritium filled capsule. In the nanoseconds that followed, the capsule imploded and released a neutron yield of nearly 3x10 15 , or approximately 8,000 joules of neutron energy -- approximately…
