1Petawatt and exawatt class lasers worldwide显示文摘In the 2015 review paper‘Petawatt Class Lasers Worldwide’a comprehensive overview of the current status of highpower facilities of>200 TW was presented.This was largely based on facility specifications,with some description of their uses,for instance in fundamental ultra-high-intensity interactions,secondary source generation,and inertial confinement fusion(ICF).With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification(CPA),which made these lasers possible,we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed.We are now in the era of multi-petawatt facilities coming online,with 100 PW lasers being proposed and even under construction.In addition to this there is a pull towards development of industrial and multi-disciplinary applications,which demands much higher repetition rates,delivering high-average powers with higher efficiencies and the use of alternative wavelengths:mid-IR facilities.So apart from a comprehensive update of the current global status,we want to look at what technologies are to be deployed to get to these new regimes,and some of the critical issues facing their development.Colin N.Danson Constantin Haefner Jake Bromage Thomas Butcher Jean-Christophe FChanteloup Enam A.Chowdhury Almantas Galvanauskas Leonida A.Gizzi Joachim Hein David I.Hillier Nicholas W.Hopps Yoshiaki Kato Efim A.Khazanov Ryosuke Kodama Georg Korn Ruxin Li Yutong Li Jens Limpert Jingui Ma Chang Hee Nam David Neely Dimitrios Papadopoulos Rory R.Penman Liejia Qian Jorge J.Rocca andrey A.Shaykin Craig W.Siders Christopher Spindloe Sándor Szatmári Raoul M.G.M.Trines Jianqiang Zhu Ping Zhu Jonathan D.Zuegel 2019High Power Laser Science and Engineering2019,7,3:33

5Direct imaging of shock wave splitting in diamond at Mbar pressure显示文摘Understanding the behavior of matter at extreme pressures of the order of a megabar(Mbar)is essential to gain insight into various physical phenomena at macroscales—the formation of planets,young stars,and the cores of super-Earths,and at microscales—damage to ceramic materials and high-pressure plastic transformation and phase transitions in solids.Under dynamic compression of solids up to Mbar pressures,even a solid with high strength exhibits plastic properties,causing the induced shock wave to split in two:an elastic precursor and a plastic shock wave.This phenomenon is described by theoretical models based on indirect measurements of material response.The advent of x-ray free-electron lasers(XFELs)has made it possible to use their ultrashort pulses for direct observations of the propagation of shock waves in solid materials by the method of phase-contrast radiography.However,there is still a lack of comprehensive data for verification of theoretical models of different solids.Here,we present the results of an experiment in which the evolution of the coupled elastic-plastic wave structure in diamond was directly observed and studied with submicrometer spatial resolution,using the unique capabilities of the x-ray free-electron laser(XFEL).The direct measurements allowed,for the first time,the fitting and validation of the 2D failure model for diamond in the range of several Mbar.Our experimental approach opens new possibilities for the direct verification and construction of equations of state of matter in the ultra-high-stress range,which are relevant to solving a variety of problems in high-energy-density physics.Sergey Makarov Sergey Dyachkov Tatiana Pikuz Kento Katagiri Hirotaka Nakamura Vasily Zhakhovsky Nail Inogamov Victor Khokhlov Artem Martynenko Bruno Albertazzi Gabriel Rigon Paul Mabey Nicholas JHartley Yuichi Inubushi Kohei Miyanishi Keiichi Sueda Tadashi Togashi Makina Yabashi Toshinori Yabuuchi Takuo Okuchi Ryosuke Kodama Sergey Pikuz Michel Koenig Norimasa Ozaki 2023Matter and Radiation at Extremes2023,8,6:0
6Feasibility study of laser-driven neutron sources for pharmaceutical applications显示文摘We predict the production yield of a medical radioisotope^(67)Cu using^(67)Zn(n,p)^(67)Cu and ^(68)Zn(n,pn)^(67)Cu reactions with fast neutrons provided from laser-driven neutron sources.The neutrons were generated by the p+9Be and d+9Be reactions with high-energy ions accelerated by laser–plasma interaction.We evaluated the yield to be(3.3±0.5)×10^(5) atoms for^(67)Cu,corresponding to a radioactivity of 1.0±0.2 Bq,for a Zn foil sample with a single laser shot.Using a simulation with this result,we estimated^(67)Cu production with a high-frequency laser.The result suggests that it is possible to generate^(67)Cu with a radioactivity of 270 MBq using a future laser system with a frequency of 10 Hz and 10,000-s radiation in a hospital.Takato Mori Akifumi Yogo Yasunobu Arikawa Takehito Hayakawa Seyed R.Mirfayzi Zechen Lan Tianyun Wei Yuki Abe Mitsuo Nakai Kunioki Mima Hiroaki Nishimura Shinsuke Fujioka Ryosuke Kodama 2023High Power Laser Science and Engineering2023,11,2:0
