Preplasma effects on laser ion generation from thin foil targets

Under typical experimental conditions related to the interaction of a short pulse laser with a nanometer foil target, the assumption of a target step-function number density profile ceases to be

Plasma optical shutter in ultraintense laser-foil interaction

We report on a plasma optical shutter to reduce the intensity level of a nanosecond-duration pedestal of amplified spontaneous emission (ASE) using an ultrathin foil. The foil is ionized by the ASE

Laser electron acceleration in the prepulse produced plasma corona

The generation of hot electrons at grazing incidence of a subpicosecond relativistic-intense laser pulse onto the plane solid target is analyzed for the parameters of the petawatt class laser

Contrast enhancement of ultra-intense laser pulses by relativistic plasma shutter

An increasing intensity of the laser systems becomes available for experiments in the fields of particle acceleration, radiation sources and many other applications. The higher intensity of the laser

Optimisation of Thin Plastic Foil Targets for Production of Laser-Generated Protons in the GeV Range

In order to realistically simulate the interaction of a femtosecond laser pulse with a nanometre-thick target it is necessary to consider a target preplasma formation due to the nanosecond long

Comparison of ion acceleration from nonexpanded and expanded thin foils irradiated by ultrashort petawatt laser pulse

It is usually assumed that ions are accelerated most efficiently in the case of non-expanded targets irradiated by femtosecond ultra-intense laser pulse, alternatively with only short scale preplasma

Electron acceleration at grazing incidence of a subpicosecond intense laser pulse onto a plane solid target

Generation of hot electrons at grazing incidence of a subpicosecond relativistic-intense laser pulse onto a plane solid target is analyzed for the parameters of petawatt class laser systems. We study

The effect of pre-plasma formation under nonlocal transport conditions for ultra-relativistic laser-plasma interaction

Interaction of high-power lasers with solid targets is in general strongly affected by the limited contrast available. The laser pre-pulse ionizes the target and produces a pre-plasma which can

Proton acceleration enhanced by a plasma jet in expanding foils undergoing relativistic transparency

Ion acceleration driven by the interaction of an ultraintense (2 × 1020 W cm−2) laser pulse with an ultrathin ( ≤ 40 ?> nm) foil target is experimentally and numerically investigated. Protons
