“…The Laser for Fast Ignition EXperiment (LFEX) is designed to have a 1 ps rise time and 2 × 2 segmented dielectric gratings. Commissioning started in 2005 and delivered petawatt operation in 2010 [93] , with full operational capability expected by the end of 2014 [94] . The beam is focused to target by a 4 m off-axis parabola, giving a spot of 30-60 µm in a 5 kJ beam in 1-20 ps, providing powers of 1-5 PW (although final specification is to deliver 10 kJ).…”

The use of ultra-high intensity laser beams to achieve extreme material states in the laboratory has become almost routine with the development of the petawatt laser. Petawatt class lasers have been constructed for specific research activities, including particle acceleration, inertial confinement fusion and radiation therapy, and for secondary source generation (x-rays, electrons, protons, neutrons and ions). They are also now routinely coupled, and synchronized, to other large scale facilities including megajoule scale lasers, ion and electron accelerators, x-ray sources and z-pinches. The authors of this paper have tried to compile a comprehensive overview of the current status of petawatt class lasers worldwide. The definition of 'petawatt class' in this context is a laser that delivers >200 TW.

“…The idea of the fast ignition seems to be quite elegant, and direct-drive fast-ignition could provide potentially high energy gain with small driver, but the development of PW-level high power laser is indispensable. Osaka University is strongly promoting a fast ignition campaign [7]. Design and construction of LFEX laser has started in 2003, and in 2008 target irradiation with high-power beam started.…”

Abstract.A new strategic energy plan decided by the Japanese Cabinet in 2014 strongly supports the steady promotion of nuclear fusion development activities, including the ITER project and the Broader Approach activities from the long-term viewpoint. Atomic Energy Commission (AEC) in Japan formulated the Third Phase Basic Program so as to promote an experimental fusion reactor project. In 2005 AEC has reviewed this Program, and discussed on selection and concentration among many projects of fusion reactor development. In addition to the promotion of ITER project, advanced tokamak research by JT-60SA, helical plasma experiment by LHD, FIREX project in laser fusion research and fusion engineering by IFMIF were highly prioritized. Although the basic concept is quite different between tokamak, helical and laser fusion researches, there exist a lot of common features such as plasma physics on 3-D magnetic geometry, high power heat load on plasma facing component and so on. Therefore, a synergetic scenario on fusion reactor development among various plasma confinement concepts would be important. IntroductionJapanese government is promoting fusion research and development based on so-called Phase Basic Program formulated by Atomic Energy Commission (AEC). Currently the third phase basic program started in 1992 has been on progress. This program sets forth key elements of research and development for a DEMO reactor, and is aiming at achieving necessary conditions for the self-ignition and at realizing the long pulse burning plasmas in a tokamak experimental reactor.Based on this principal policy, the ITER has been assigned as a core device in the third phase basic program. While, just before the start of ITER project, this third phase basic program has been reviewed, and report entitled by Future Fusion Research and Development Strategy in the Third Phase Basic Program of Fusion Research and Development was issued in 2005 [1]. In this report action items of recent research and development including ITER project have been described.In 2011 we had a Great East Japan Earthquake, and quite serious nuclear accidents have taken place in Fukushima nuclear power plants. Therefore, in Japan the government has reconsidered energy strategy, and the Cabinet has decided a new strategic energy plan in 2014. In this new strategic energy plan, the Government declares that although nuclear power is expected to be a baseload power supply, Japan will minimize its dependency on nuclear power. While, concerning to nuclear fusion, this report declares that the Japanese government steadily promotes nuclear fusion development activities, including the ITER project, which is being implemented through international cooperation, and the Broader Approach Activities from the long-term viewpoint [2].

“…The neutron generation by laser implosion have been demonstrated experimentally in various single shot lasers [Nakai 2004, Meyerhofer 2011, Azechi 2009] being the number of neutrons generated per one pulse much higher than those of the other laser driven cases. Therefore, the implosion neutron source is in principle the most intense among the various laser neutron sources.…”

The basics of laser driven neutron sources, properties and possible applications are discussed. We describe the laser driven nuclear processes which trigger neutron generation, namely, nuclear reactions induced by laser driven ion beam (ion n), thermonuclear fusion by implosion and photo-induced nuclear (gamma n) reactions. Based on their main properties, i.e. point source (< 100μm) and short durations (< ns), different applications are described, such as radiography, time-resolved spectroscopy and pump-probe experiments. Prospects on the development of laser technology suggest that, as higher intensities and higher repetition rate lasers become available (for example, using DPSSL technology), laser driven methodologies may provide neutron fluxes comparable to that achieved by accelerator driven neutron sources in the near future.
