Nanostructured and microstructured thin foils have been fabricated and used experimentally as targets to manipulate the spatial profile of proton bunches accelerated through the interaction with high intensity laser pulses (6×10^{19} W/cm^{2}). Mono

In this work, we experimentally study the effects of the nitrogen concentration in laser wakefield acceleration of electrons in a gas mixture of hydrogen and nitrogen. A 15 TW peak power laser pulse is focused to ionize the gas, excite a plasma wave

The properties of laser wakefield accelerated electrons in supersonic gas flows of hydrogen and helium are investigated. At identical backing pressure, we find that electron beams emerging from helium show large variations in their spectral and spati

Laser energy absorption to fast electrons during the interaction of an ultra-intense (10 ^20 W cm ^−2 ), picosecond laser pulse with a solid is investigated, experimentally and numerically, as a function of the plasma density scale length at the ir

A laser pulse traveling through a plasma can excite large amplitude plasma waves that can be used to accelerate relativistic electron beams in a very short distance—a technique called laser wakefield acceleration. Many wakefield acceleration experi

Tracking primary radiation-induced processes in matter requires ultrafast sources and high precision timing. While compact laser-driven ion accelerators are seeding the development of novel high instantaneous flux applications, combining the ultrasho

High-power Ti:sapphire laser pulses (150 mJ in 150 fs) were focused into a gas jet of He, ${\mathrm{N}}_{2}$, ${\mathrm{CO}}_{2}$, ${\mathrm{O}}_{2}$, ${\mathrm{SF}}_{6}$, or Ar emitted from a pulsed nozzle. The xuv spectra that were generated are re

Laser pre‐pulse is a major issue in experiments on laser‐generation of protons, often limiting the performances of laser sources. In this paper, we show how we can actively use a low intensity prepulse (
