This includes the treatment of the propagation of the light coming from a well-defined region of plasma through the rest of the plasma and all the optics of the imaging system. The convolution of computed magnitudes with the plasma and diagnostics transfer functions enables the comparison between experiments and simulations. This new tool is indispensable in the study of the propagation of intense laser beams in plasma media. 1 – Introduction 2 – L’expérience LULI La propagation de faisceaux lasers intenses à travers des L'expérience d'étude de la propagation d'un faisceau laser à plasmas sous-denses présente beaucoup d'intérêt pour la fusion travers un plasma sous-dense préformé a été menée sur par confinement inertiel (FCI) [1].

  • 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.

  • 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.

Gutachten: Prof. Dr. Markus Roth Tag der Einreichung: 27.11.2012 Tag der Prüfung: 21.12.2012 Darmstadt — D 17 Dedicated to the memory of my grandmother Marieta Ionita Zusammenfassung Materie unter extremen Druck und Temperatur Bedingungen bietet einen aufregenden Forschungsbereich sowohl für die Grundlagen- als auch die angewandte Forschung. Die fun- damentalen physikalischen Eigenschaften solcher Zustände hoher Energiedichte (High Energy Density – HED states) – wie die Zustandsgleichung (equation of state – EOS) – sind von großer Bedeutung sowohl für theoretische als auch für experimentelle Untersuchungen. Solche extreme Zustände können unter Laborbedingungen nur in dynamischen Experimenten mit besonders leistungsfähigen Treibern erreicht werden. Das GSI Helmholtzzentrum für Schw- erionenforschung (GSI) mit seinem einzigartigen Schwerionensynchrotron SIS-18 and dem Hohe Energie Petawatt Laser PHELIX bietet ideale Möglichkeiten zur Erforschung dieser Ma- teriezustände. Das Ziel dieser Arbeit ist, die thermophysikalischen Eigenschaften von Metallen im Bereich der Warmen Dichten Materie (WDM), die sich durch Temperaturen von 1-50 eV und Dichten nahe deren der Festkörper charakterisiert, mittels interferometrischer Messungen zu untersuchen. Am Hochtemperaturmessplatz HHT des GSI wurden Druck- und Temperaturmessungen im Bere- ich des kritischen Punktes von Metallen durchgeführt.

  • Recent Advances in Laser-Induced Surface Damage of KH2PO4 Crystal
    applied sciences Review Recent Advances in Laser-Induced Surface Damage of KH2PO4 Crystal Mingjun Chen *, Wenyu Ding, Jian Cheng, Hao Yang and Qi Liu School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150001, China; [email protected] (W.D.); [email protected] (J.C.); [email protected] (H.Y.); [email protected] (Q.L.) * Correspondence: [email protected]; Tel.: +86-0451-86403252 Received: 22 August 2020; Accepted: 21 September 2020; Published: 23 September 2020 Abstract: As a hard and brittle material, KDP crystal is easily damaged by the irradiation of laser in a laser-driven inertial confinement fusion device due to various factors, which will also affect the quality of subsequent incident laser. Thus, the mechanism of laser-induced damage is essentially helpful for increasing the laser-induced damage threshold and the value of optical crystal elements. The intrinsic damage mechanism of crystal materials under laser irradiation of different pulse duration is reviewed in detail. The process from the initiation to finalization of laser-induced damage has been divided into three stages (i.e., energy deposition, damage initiation, and damage forming) to ensure the understanding of laser-induced damage mechanism. It is clear that defects have a great impact on damage under short-pulse laser irradiation. The burst damage accounts for the majority of whole damage morphology, while the melting pit are more likely to appear under high-fluence laser. The three stages of damage are complementary and the multi-physics coupling technology needs to be fully applied to ensure the intuitive prediction of damage thresholds for various initial forms of KDP crystals.

  • The Measurement of Few-Cycle Pulse Duration Is a Real Challenge Even with the Most Powerful Technique
    5 Technological basis for the primary sources The measurement of few-cycle pulse duration is a real challenge even with the most powerful technique. The reasons for this are the required ultra-broad phase matching bandwidth, ideally all-reflective setup and minimal introduced dispersion by the generation of the non-linear signal. There are some versions of FROG as SHG [12] and TG [13] that under special conditions – such as few-µm thick non-linear medium – can support pulses with about a single optical cycle duration [14]. A much more complex, but even more detailed technique for sub-2-cycle pulses is based on the generation of a single XUV attosecond pulse and using the laser electric fields to shift the energy spectrum of free electrons produced by the XUV probe pulse. Measuring the electron spectrum as a function of the delay between the laser and the XUV pulse a so called “attosecond streaking" curve is obtained [15]. This determines the electric field of the laser and even the absolute phase or carrier envelope phase and the strength of the electric field in the point of measurement. Attosecond streaking belongs to the conventional approaches that to characterize a short pulse uses an even shorter pulse. At the end of this brief overview the complete measurement of long pulse durations (100 ps– 1 ns) with large time-bandwidth product (TBP) is discussed. It should be noted that a fast photodiode with an oscilloscope can measure the temporal intensity without the phase for these pulse durations – assuming there are no fast changes.

  • Mid-Infrared Femtosecond Laser- Induced Damages in As2
    www.nature.com/scientificreports OPEN Mid-infrared femtosecond laser- induced damages in As2S3 and As2Se3 chalcogenide glasses Received: 28 March 2017 Chenyang You1,2, Shixun Dai1,2, Peiqing Zhang1,2, Yinsheng Xu1,2, Yingying Wang1,2, Dong Accepted: 14 June 2017 Xu1,2 & Rongping Wang1,2 Published online: 26 July 2017 In this paper, we report the frst measurements of mid-infrared (MIR) femtosecond laser-induced damage in two typical chalcogenide glasses, As2S3 and As2Se3. Damage mechanism is studied via optical microscopy, scanning electron microscopy and elemental analysis. By irradiating at 3, 4 and 5 μm with 150 fs ultrashort pulses, the evolution of crater features is presented with increasing laser fuence. The dependence of laser damage on the bandgap and wavelength is investigated and fnally the laser-induced damage thresholds (LIDTs) of As2S3 and As2Se3 at 3 and 4 μm are calculated from the experimental data. The results may be a useful for chalcogenide glasses (ChGs) applied in large laser instruments to prevent optical damage. ChGs have attracted intensive research interests in past decades due to their low phonon energies, high linear and nonlinear refractive indexes and wide transparency in the infrared region. Tey have shown great potentials for applications in biosensors1, atmosphere pollution monitoring2, frequency metrology3, and temperature sensors4. As a matter of fact, waveguide or fber based devices have been explored based on high nonlinearity of ChGs, for example, mid-infrared laser sources like supercontinuum generation, and high speed signals processor using chalcogenide waveguide-based devices. However, one of the drawbacks of ChGs is their relatively weak mechan- ical properties.

Subsurface impurity defects inevitably introduced in the practical polishing process incur strong thermal absorption for incident lasers, seriously lowering the laser-induced damage threshold (LIDT). Here, we simulate the temperature and thermal stress distributions involved in the laser irradiation process to investigate the effect of impurity defects on laser damage resistance. Then, HF-based etchants (HF:NH4F) are applied to remove the subsurface impurity defects and the surface quality, impurity contents and laser damage resistance of etched silica surfaces are tested. The results indicate that the presence of impurity defects could induce a dramatic rise of local temperature and thermal stress. The maximum temperature and stress can reach up to 7073 K and 8739 MPa, respectively, far higher than the melting point and compressive strength of fused silica, resulting in serious laser damage.
