The interaction of intense laser pulses with thin foils is accompanied by the acceleration of ions to energies of tens of megaelectronvolts [1–4]. The production of high-quality beams of ions
Plasma produced by short laser pulses from thin homogeneous foils with light and heavy ions is capable of generating quasi-monoenergetic light ions. This happens for the tail of light ions near the front of heavy ions. It was found that this effect is well pronounced for a moderate laser intensity (~10 18 W/cm 2 ) and pulse duration (~1 ps) by using a 2D particle-in-cell simulation of the laser...
متن کاملRelativistic positron production with ultra-intense short-pulse lasers
Ultra-intense laser interactions with solid foils are studied as a means to produce relativistic positron plasmas, which has been proposed as a potential laboratory for understanding positron-electron plasma aspects of gamma-ray bursts [1]. Initial experiments with high energy Nd:glass lasers have revealed a strong dependence of the positron yield, and energy distribution, on the thin-foil targ...
متن کاملK-alpha backlighter optimization using high-energy picosecond laser pulses in experiments at the PHELIX laser facility
Development of laser driven high-brightness fast x-ray sources is a key application of the PHELIX laser for experiments in combination with the heavy ion accelerator. X-ray diagnostics of high-energy density states of matter produced with intense heavy ion beams from GSI or FAIR will require multi-keV x-ray energies to penetrate the dense plasma [1]. Recent development of backlighter sources at...
متن کاملHigh-intensity laser-driven proton acceleration: influence of pulse contrast.
Proton acceleration from the interaction of ultra-short laser pulses with thin foil targets at intensities greater than 10(18) W cm(-2) is discussed. An overview of the physical processes giving rise to the generation of protons with multi-MeV energies, in well defined beams with excellent spatial quality, is presented. Specifically, the discussion centres on the influence of laser pulse contra...
متن کاملEnhanced laser-ion acceleration in thin foils of reduced surface
Ion acceleration in the interaction of ultrashort intense laser pulses (~ 2×10 W/cm, 10s-100s fs) with thin solid foils of limited transverse extend (~ 10s of μm) is measured experimentally and studied numerically (by PIC simulations). Reducing the target surface area allows hot electrons to be reflected from target edges during or shortly after the laser pulse. This transverse refluxing in suc...
