Ultrahigh peak power production from compact short-pulse laser systems
Introduction of chirped-pulse amplification (CPA) enabled the latest revolution in production of high peak powers from lasers through amplification of very short (femtosecond) laser pulses to pulse energies previously available only from long-pulse lasers. CPA has rapidly bridged the gap from its initial modest demonstrations to multi-terawatt and petawattscale systems in research facilities an...
متن کاملMonoenergetic Proton Beams from Laser Driven Shocks
Laser driven ion acceleration (LDIA) has the potential to deliver compact and affordable accelerators for applications in many fields of science and medicine. Specifically, radiotherapy of cancerous tumors requires ion energies in the range of 200-300 MeV/a.m.u. and with energy spreads on the order of 5%, parameters thus far beyond the LDIA experimental results using the most powerful lasers in...
متن کاملEnergy coupling in short pulse laser solid interactions and its impact for space debris removal.
Significant advances have been made over the last decade to improve the performance, efficiency, and contrast of high peak and average power laser systems, driven by their use in a wide variety of fields, from the industrial to the scientific. As the contrast of the lasers has improved, interactions with contrasts of 1012 are now routinely undertaken. At such high contrasts, there is...
متن کاملEnergetic Proton Generation in Ultra-Intense Laser-solid Interactions
An explanation for the energetic ions observed in the PetaWatt experiments is presented. In solid target experiments with focused intensities exceeding 10 W/cm, high-energy electron generation, hard bremsstrahlung, and energetic protons have been observed on the backside of the target. In this report, we attempt to explain the physical process present that will explain the presence of these ene...
متن کاملComment on "generating high-current monoenergetic proton beams by a circularly polarized laser pulse in the phase-stable acceleration regime".
A new ion acceleration method, namely, phase-stable acceleration, using circularly-polarized laser pulses is proposed. When the initial target density n(0) and thickness D satisfy a(L) approximately (n(0)/n(c))D/lambda(L) and D>l(s) with a(L), lambda(L), l(s), and n(c) the normalized laser amplitude, the laser wavelength in vacuum, the plasma skin depth, and the critical density of the incident...
