Joint thematic Workshop of Institut Lasers Plasmas, and LaserLab-Europe NA3 networking activity : Thematic Network on High Energy Lasers Next generation high energy lasers for basic research : Need for versatile high rep rate facilities Bordeaux University, September 3rd, 2010 1. RATIONALE The French government has issued a call for medium-size Research Infrastructures, which may represent a major opportunity to boost High Energy Density research, both at French and European levels. Under the aegis of Institut Lasers Plasmas (France), and LaserLab- Europe 2 , a dedicated workshop should unravel the general needs and scientific cases for a next generation HED laser facility of high repetition rates (one shot per few minutes) but moderate energies, and discuss how such a facility can be coordinated with other HED facilities and programs at French and European levels. 2. SCIENTIFIC CONTEXT The physics of laser-matter interaction in the domain of High Energy Density (HED) matter requires large scale laser facilities with laser pulses of many kilojoules. The technological frontier is now provided by such lasers systems as the National Ignition Facility (NIF), USA, and Laser MegaJoule (LMJ) near Bordeaux, or by Petawatt high energy lasers such as Omega-EP, Rochester University, USA, LFEX, Osaka University, Japan, or PETAL, Bordeaux. However, because of their extremely high operational cost and relatively low number of shots available, smaller sized facilities, so called "intermediate", are absolutely crucial to all scientific and technological developments in the field. The French national taskforce on the development of powerful lasers, ILP/GRALE, has identified four classes of high energy lasers: – Lasers of megajoule level; – Lasers of large but intermediate scale with a pulse energy larger than 10 kJ; – Lasers of kilojoule scale, such as LULI2000; – Sub-kilojoule scale lasers providing a combination of accessibility and flexibility of use. -

Yves Bréchet – Haut-Commissaire à l’Energie Atomique CEA Saclay 91191 Gif-sur-Yvette, France Thierry Massard CEA DAM-Ile de France, Bruyères le Chatel, 91297 Arpajon, France Abstract. Finite amount of fossil fuel, global warming, increasing demand of energies in emerging countries tend to promote new sources of energies to meet the needs of the coming centuries. Despite their attractiveness, renewable energies will not be sufficient both because of intermittency but also because of the pressure they would put on conventional materials. Thus nuclear energy with both fission and fusion reactors remain the main potential source of clean energy for the coming centuries. France has made a strong commitment to fusion reactor through ITER program. But following and sharing Euratom vision on fusion, France supports the academic program on Inertial Fusion Confinement with direct drive and especially the shock ignition scheme which is heavily studied among the French academic community. -
The Effect of Surface Processing Methods on the Laser Induced Damage Threshold of Fused Silica
The Effect of Surface Processing Methods on the Laser Induced Damage Threshold of Fused Silica by Weiran Duan A thesis submitted in partial fulfilment for the requirements for the degree of PhD at the University of Central Lancashire October 2014 2 To my family i Declaration I declare that while registered as a candidate for the research degree, I have not been a registered candidate or enrolled student for another award of the University or other academic or professional institution. I declare that no material contained in the thesis has been used in any other submission for an academic award and is solely my own work. Weiran Duan ii Abstract High peak power laser systems, such as National Ignition Facility (NIF), Laser Mega Joule (LMJ), and High Power laser Energy Research facility (HiPER), include a large amount of optics. Fused silica glass is one of the most common optical materials which is used in these high peak power laser systems owing to its excellent optical properties, especially for the 355nm ultraviolet laser. However, it is generally found that fused silica optics damage under irradiation with a high peak power laser beam, and the laser induced damage (LID) becomes the limit to increasing the laser power. Theoretically, the laser induced damage threshold (LIDT) of fused silica substrates is high, while it drops significantly due to the poor surface quality created in the manufacturing process. This project aims to find a series of fused silica optical surface processing techniques which are able to improve the surface quality and increase its LIDT when irradiated using high peak power lasers. -

Postnikova1 Candidate of Engineering Sciences, Senior Research Officer, Senior Research Officer 1Кyiv National University of Construction and Architecture There is short description of problem state on nonlinear dynamics in this paper. Information about some contemporary journals and recent Conferences on this subject is given. Information about 5th International Conference on Nonlinear Dynamics which was holding in National Technical University “Kharkov Polytechnic Institute” in September 2016 and impression about it are presented. The questions that were discussed at this conference are in domain of our special interests. Dynamic behaviour of non-smooth systems with discontinuous right-hand side is the main contemporary question. Many new phenomena unique to non-smooth systems are observed under variation of system parameters. Such nonlinear problems are arising in many different domains of science and engineering, for example in mechanics, physics, radio technique, biology, chemistry, economics, ecology, sociology, and so on. The investigations of nonlinear dynamics problems in general and very complex phenomenon of chaos in particular were begun quite recently – only in the end of 20-th century. Vibroimpact system is one example of nonlinear systems. It is strongly nonlinear non-smooth discontinuous system because the set of its motion differential equations contains the discontinuous right-hand side. The bifurcations of different kind occur in vibroimpact system under system parameter variation. -

We greatly acknowledge support of Institute for Laser Science Applications, LLNL. Committee on Atomic, Molecular and Optical Sciences Meeting The National Academy of Sciences Washington DC, April 5, 2011 1 Summary ü Short pulse high intensity laser solid interactions create matter under extreme conditions and generate a variety of energetic particles. ü There are a number of applications from fusion to low energy nuclear reactions. 10 ns ü Fast Ignition Inertial Confinement Fusion is one application that promises high gain fusion. ü Experiments have been encouraging but point towards complex issues than previously anticipated. ü Recent, short pulse high intensity laser matter experiments show that low coupling could be due to: - prepulse - electron source divergence. ü Experiments on fast ignition show proton focusing spot is adequate for FI.

Thesis Advancements in the Optical Damage Resistance
THESIS ADVANCEMENTS IN THE OPTICAL DAMAGE RESISTANCE OF ION BEAM SPUTTER DEPOSITED INTERFERENCE COATINGS FOR HIGH ENERGY LASERS Submitted by Drew Schiltz Department of Electrical and Computer Engineering In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Summer 2015 Master’s Committee: Advisor: Carmen Menoni Mario Marconi Mark Bradley Copyright by Drew Donald Schiltz 2015 All Rights Reserved ABSTRACT ADVANCEMENTS IN THE LASER DAMAGE RESISTANCE OF ION BEAM SPUTTER DEPOSITED INTERFERENCE COATINGS FOR HIGH ENERGY LASERS The work presented in this thesis is dedicated toward investigating, and ultimately improving the laser damage resistance of ion beam sputtered interference coatings. Not only are interference coatings a key component of the modern day laser, but they also limit energy output due to their susceptibility to laser induced damage. Thus, advancements in the fluence handling capabilities of interference coatings will enable increased energy output of high energy laser systems. Design strategies aimed at improving the laser damage resistance of Ta2O5/SiO2 high reflectors for operation at one micron wavelengths and pulse durations of several nanoseconds to a fraction of a nanosecond are presented. These modified designs are formulated to reduce effects from the standing wave electric field distribution in the coating. Design modifications from a standard quarter wave stack structure include increasing the thickness of SiO2 top layers and reducing the Ta2O5 thickness in favor of SiO2 in the top four bi-layers. The coating structures were deposited with ion beam sputtering. The modified designs exhibit improved performance when irradiated with 4 ns duration pulses, but little effect at 0.19 ns.
