Karel Jungwirth,A. Cejnarová,Libor Juha,B. Králiková,Josef Krasa,E. Krousky,P. Krupickova,Leos Laska,Karel Masek,Tomas Mocek,Miroslav Pfeifer,A. R. Präg,O. Renner,Karel Rohlena,Bedřich Rus,Jiri Skala,P. Straka,J. Ullschmied +17 more
TL;DR: The Prague Asterix Laser System (PALS) as mentioned in this paper is a high-power laser system with up to 1.2 kJ of energy in ∼400 ps pulses at the wavelength of 1.315 μm.
Journal ArticleDOI
Fast ignition by laser driven particle beams of very high intensity
Heinrich Hora,J. Badziak,M. N. Read,Yutong Li,T. J. Liang,Yu Cang,Hong Liu,Zheng-Ming Sheng,Jie Zhang,Frederick Osman,George H. Miley,Weiyan Zhang,Xian-Tu He,Hansheng Peng,S. Glowacz,S. Jabłoński,Jerzy Wolowski,Z. Skladanowski,Karel Jungwirth,Karel Rohlena,J. Ullschmied +20 more
TL;DR: In this article, anomalous observations using the fast ignition for laser driven fusion energy are interpreted and experimental and theoretical results are reported which are in contrast to the very numerous effects usually observed at petawatt-picosecond laser interaction with plasmas.
Journal ArticleDOI
Effects of ps and ns laser pulses for giant ion source
Heinrich Hora,J. Badziak,F. P. Boody,R. Höpfl,Karel Jungwirth,B. Králiková,J. Krasa,Leos Laska,Piotr Parys,V. Perina,Miroslav Pfeifer,Karel Rohlena,Jiri Skala,J. Ullschmied,Jerzy Wolowski,Eugeniusz Woryna +15 more
TL;DR: In this paper, a skin layer process was used to explain the relativistic self-focusing and nonlinear force effects of very energetic highly charged fast ions, separated by their charge number Z, from ns laser pulses.
Journal ArticleDOI
Fusion energy using avalanche increased boron reactions for block-ignition by ultrahigh power picosecond laser pulses
Heinrich Hora,Georg Korn,Lorenzo Giuffrida,Daniele Margarone,Antonino Picciotto,Josef Krasa,Karel Jungwirth,Jiri Ullschmied,Paraskevas Lalousis,Shalom Eliezer,George H. Miley,Stavros Moustaizis,Gerard Mourou +12 more
TL;DR: In this article, it was shown that secondary avalanche reactions are happening and confirming the results of high-gain, neutron-free, clean, safe, low-cost, and long-term available energy.
Journal ArticleDOI
Generation of multiply charged ions at low and high laser-power densities
Leos Laska,Karel Jungwirth,B. Králiková,J. Krasa,Miroslav Pfeifer,Karel Rohlena,Jiri Skala,J. Ullschmied,J. Badziak,Piotr Parys,Jerzy Wolowski,Eugeniusz Woryna,Santo Gammino,Lorenzo Torrisi,F. P. Boody,Heinrich Hora +15 more
TL;DR: The PERUN and PALS iodine laser systems and a Nd : YAG laser have been used for studies of ions emitted from various single element laser plasmas, at both low (IL~109 W cm−2) and high (IL>2×1014 W cm −2) laser intensities, at which the existence of an ''optimum focus position'' in front of the target surface is consistent with the idea that laser interaction with a prepulse-produced plasma improves the conditions for self-focusing as discussed by the authors.
