Diode array alternative to paint removal solid-state cw laser

Description: The purpose of this memo is to highlight an alternative to the approach for cw laser paint removal. The point to be made is that a direct diode design is feasible and can be far more competitive than a solid-state laser based system. Through by-passing the use of a solid-state laser media, we immediately gain a factor of about five in system efficiency based on measured optical-to-optical efficiencies of our average power diode pumped lasers. This permits a massive reduction in system cooling r… more

Atomic vapor laser isotope separation using resonance ionization

Description: Atomic vapor laser isotope separation (AVLIS) is a general and powerful technique. A major present application to the enrichment of uranium for light-water power-reactor fuel has been under development for over 10 years. In June 1985, the Department of Energy announced the selection of AVLIS as the technology to meet the nation's future need for enriched uranium. Resonance photoionization is the heart of the AVLIS process. We discuss those fundamental atomic parameters that are necessary for de… more

High average power diode pumped solid state lasers for CALIOPE

Description: Diode pumping of solid state media offers the opportunity for very low maintenance, high efficiency, and compact laser systems. For remote sensing, such lasers may be used to pump tunable non-linear sources, or if tunable themselves, act directly or through harmonic crystals as the probe. The needs of long range remote sensing missions require laser performance in the several watts to kilowatts range. At these power performance levels, more advanced thermal management technologies are required … more

LLNL medical and industrial laser isotope separation: large volume, low cost production through advanced laser technologies

Description: The goal of this LDRD project was to demonstrate the technical and economical feasibility of applying laser isotope separation technology to the commercial enrichment (>lkg/y) of stable isotopes. A successful demonstration would well position the laboratory to make a credible case for the creation of an ongoing medical and industrial isotope production and development program at LLNL. Such a program would establish LLNL as a center for advanced medical isotope production, successfully levera… more

Production of high-value isotopically separated materials

Description: The purpose of this project was to complete the development of the laser systems and separator systems needed to investigate the potential for the economical separation of high value isotopes used in medical and industrial applications, then demonstrate this separation capability. The project was to focus on the isotopic purification of lead for use as solder in high- end electronics, and on the isotopic enrichment of thallium for medical applications. Ultimately the goal is to demonstrate the … more

Five-Year Program for Federal Offshore Oil and Gas Leasing: Status and Issues in Brief

Description: This report summarizes developments in the offshore oil leasing 2017-2022 program and considers selected congressional issues and actions related to the program. President Trump issued an executive order on April 28, 2017, directing the Secretary of the Interior to review and consider revising the 2017-2022 program. The 115th Congress could influence the five-year program by enacting legislation to alter the program, as well as by conducting oversight.

Display of the Confederate Flag at Federal Cemeteries in the United States

Description: This report discusses policies regarding the display of the Confederate Flag at national cemeteries. If a state observes a Confederate Memorial Day, National Park Service (NPS) cemeteries in the state may permit a sponsoring group to decorate the graves of Confederate veterans with small Confederate flags. Additionally, such flags may also be displayed on the nationally observed Memorial Day, to accompany the U.S. flag on the graves of Confederate veterans.
