Hydrodynamic impacts of short laser pulses on plasmas

We determine conditions allowing to simplify the description of the impact of a short and arbitrarily intense laser pulse onto a cold plasma at rest. If both the initial plasma density and pulse profile have plane simmetry, then suitable matched upper bounds on the maximum and the relative variations of the initial density, as well as the intensity and duration of the pulse, ensure a strictly hydrodynamic evolution of the electron fluid (without wave-breaking or vacuum-heating) during its whole interaction with the pulse, while ions can be regarded as immobile. We use a recently developed fully relativistic plane model whereby the system of the (Lorentz-Maxwell and continuity) PDEs is reduced into a family of highly nonlinear but decoupled systems of non-autonomous Hamilton equations with one degree of freedom, with the light-like coordinate ξ = ct−z instead of time t as an independent variable, and new apriori estimates (eased by use of a Liapunov function) of the solutions in terms of the input data (initial density and pulse profile). If the laser spot radius R is finite but not too small the same conclusions hold for the part of the plasma close to the axis z of cylindrical symmetry. These results may help in drastically simplifying the study of extreme acceleration mechanisms of electrons.

“…2 In fact, huge investments aiming at the construction of table-top particle accelerators based on Wake Field Acceleration are being made all over the world. For instance, in Europe the large network of research centers "European Plasma Research Accelerator with eXcellence In Applications" (EUPRAXIA) has been created to develop the associated technologies and has just issued its expected Conceptual Design Report of reliable accelerators of this kind [6,7,8]. Among the present and future applications of accelerators we mention:…”

Light-front approach to relativistic electrodynamics

We illustrate how our recent light-front approach simplifies relativistic electrodynamics with an electromagnetic (EM) field F µν that is the sum of a (even very intense) plane travelling wave F µν t (ct−z) and a static part F µν s (x, y, z); it adopts the light-like coordinate ξ = ct−z instead of time t as an independent variable. This can be applied to several cases of extreme acceleration, both in vacuum and in a cold diluted plasma hit by a very short and intense laser pulse (slingshot effect, plasma wave-breaking and laser wake-field acceleration, etc.)1. E, B are constant or vary "slowly" in space/time; 2. the motion of the particle keeps non-relativistic;3. E, B are so small that nonlinear effects in E, B are negligible;4. E, B are monochromatic waves, or very slow modulations thereof.

“…Nowadays, quasi-monoenergetic high-energy electron bunches are routinely produced in many laboratories with multi-terawatt (multi-TW) and petawatt (PW) lasers [4][5][6][7][8][9][10][11][12]. There are also large projects dedicated to laser-plasma acceleration technology like EuPRAXIA (European Plasma Research Accelerator with eXcellence In Applications) project which is expected to provide a large research infrastructure including a compact European plasma accelerator with superior beam quality [13,14].…”

Experimental study of strongly mismatched regime of laser-driven wakefield acceleration

Laser wakefield acceleration of electrons is studied experimentally in the strongly mismatched regime. Up to 20 J, 60 fs laser pulses are focussed at the input of a gas cell with the f /46 focussing system. The resulting 44 µm focal spot at the cell entrance is about two times greater than the matched spot size. Experimental results are supported by 3D particle-in-cell (PIC) simulations of the laser-plasma dynamics as well as by numerical simulations of the gas distribution inside the gas cell. Special attention is paid to the accuracy of spectra reconstruction affected by low pointing stability of the accelerated electron beam. It is demonstrated experimentally that the electron energy in the mismatched regime can be higher than that in the matched one and can reach GeV level for the used laser parameters.
