Simulations of transitional self-modulated laser wakefield acceleration driven by laser pulses of a few terawatts are discussed, comparing a downramp-based injection regime with an ionization injection regime. We demonstrate that a configuration usin

Laser wakefield electron acceleration with ionization injection has rarely been studied in the low-power, self-modulated case. We performed simulations of such regimes using a mixture of He and N2 gases and driven by laser pulses with peak powers aro

Side-view density profiles of a laser-induced plasma were measured by a home-built, time-resolved, Mach–Zehnder-like interferometer. Due to the pump-probe femtosecond resolution of the measurements, the plasma dynamics was observed, along with the

We discuss the results of simulating a laser wakefield accelerator in the 50 MeV range suitable for repetition rates > 10 Hz using commercial lasers and compare with other approaches for this purpose.

We review the fundamentals of electron beam generation in self-modulated laser wakefield acceleration (SM-LWFA) using laser pulses with peak powers on the TW and sub-TW scale. The results of several new particle-in-cell simulations for λ = 0.8 µm a

Electron beams generated by laser wakefield acceleration can induce a photoneutron reaction to convert 100Mo into 99Mo. Multi-pC, several-MeV electron beams, obtained from particle-in-cell simulations, could generate bremsstrahlung gamma photons with

This work reports the development of a modified Mach-Zehnder interferometer aimed at determining the density of gas targets and laser generated plasmas, in time and space. This interferometer will compose our laboratory implementations for laser wake

Ultrashort laser pulses interact with matter in unique, nonselective ways, due to electronic direct excitation in an ultrafast time scale. Additionally, these pulses can cover peak powers from kW to PW, allowing its use to induce from nonlinear optic
