“…Further increase of the contrast intensity can be obtained by using plasma mirrors in the path of the amplified compressed pulse beam [23][24][25]. For a high intensity laser pulse, incident on an AR coated glass slab, the ionization of the dielectric material takes place on the leading edge of the pulse.…”

“…Because contrast is crucial for accessing high field physics in desired targets, it was under intense investigation throughout the world. Some techniques for improving the intensity contrast of high power femtosecond lasers, such as saturable absorbers [17,18], XPW [19][20][21], OPCPA [4,22] were tested inside the chirped amplifier chains, whereas plasma mirrors, based on self-induced plasma shuttering, were proposed after the temporal compression of amplified chirped laser pulses [23][24][25].…”

“…Several facilities, like LULI atÉcole Polytechnique (France) [47], Trident at Los Alamos National Laboratory (NM) [48] , HERCULES at the University of Michigan (MI) [49], Titan at Lawrence Livermore National Laboratory (CA) [50], OMEGA EP at the Laboratory for Laser Energetics (NY) [51], Orion at the Atomic Weapons Establishment (UK) [52] and, of course, Scarlet at The Ohio State University (OH) [53] already have this pulse cleaning capability typically obtained through nonlinear optical processes, such as harmonic generation and third order cross-polarized wave generation [54], or with plasma mirrors [55,56].…”

Ultra-intense laser (> 10 18 W/cm 2 ) interactions with matter are capable of producing relativistic electrons which have a variety of applications in state-of-the-art scientific and medical research conducted at universities and national laboratories across the world. Control of various aspects of these hot-electron distributions is highly desired to optimize a particular outcome. Hot-electron generation in low-contrast interactions, where significant amounts of under-dense pre-plasma are present, can be plagued by highly non-linear relativistic laser-plasma instabilities and quasi-static magnetic field generation, often resulting in less than desirable and predictable electron source characteristics. High-contrast interactions offer more controlled interactions but often at the cost of overall lower coupling and increased sensitivity to initial target conditions. An experiment studying the differences in hot-electron generation between high and low-contrast pulse interactions with solid density targets was performed on the Titan laser platform at the Jupiter Laser Facility at Lawrence Livermore National Laboratory in Livermore, CA. To date, these hot-electrons generated in the laboratory are not directly observable at the source of the interaction. Instead, indirect studies are performed using state-of-the-art simulations, constrained by the various experimental measurements. These measurements, more-often-than-not, rely on secondary processes generated by the transport of these electrons through the solid density materials which can susceptible to a variety instabilities and target material/geometry effects. Although often neglected in these types of studies, the specularly reflected light can provide invaluable insight as it is directly influenced by the interaction.In this thesis, I address the use of (personally obtained) experimental specular reflectivity measurements to indirectly study hot-electron generation in the context of high-contrast, ii relativistic laser-plasma interactions. Spatial, temporal and spectral properties of the incident and specular pulses, both near and far away from the interaction region where experimental measurements are obtained, are used to benchmark simulations designed to infer dominant hot-electron acceleration mechanisms and their corresponding energy/angular distributions. To handle this highly coupled interaction, I employed particle-in-cell modeling using a wide variety of algorithms (verified to be numerically stable and consistent with analytic expressions) and physical models (validated by experimental results) to reasonably model the interaction's sweeping range of plasma densities, temporal and spatial scales, G.

“…Recently the development of plasma mirrors for the temporal pulse cleaning has gained attention [8,[33][34][35][36]. Hence, the laser beam is weakly focused on an antireflection coated glass plate so that the peak intensity reaches about 10 15 − 10 16 W/cm 2 .…”
