In laser-wakefield acceleration, an ultra-intense laser pulse is focused into an underdense plasma in order to accelerate electrons to relativistic velocities. In most cases, the pulses consist of multiple optical cycles and the interaction is well described in the framework of the ponderomotive force where only the envelope of the laser has to be considered. But when using single-cycle pulses, the ponderomotive approximation breaks down, and the actual waveform of the laser has to be taken into… 


Identifying observable carrier-envelope phase effects in laser wakefield acceleration with near-single-cycle pulses
Driving laser wakefield acceleration with extremely short, near single-cycle laser pulses is crucial to the realisation of an electron source that can operate at kHz-repetition rate while relying on
Optical phase effects in electron wakefield acceleration using few-cycle laser pulses
Simulations performed with the particle-in-cell code Calder Circ show the feasibility of injection and acceleration of electrons in the laser wakefield created by few-femtosecond laser pulses with
Electron acceleration in sub-relativistic wakefields driven by few-cycle laser pulses
Using particle-in-cell simulations, we study the interaction of few-mJ–few-cycle laser pulses with an underdense plasma at resonant density. In this previously unexplored regime, it is found that
Carrier-envelope phase effects in plasma-based electron acceleration with few-cycle laser pulses.
It is shown that for few-cycle laser pulses the cavity shape becomes asymmetric and depends strongly on the carrier-envelope phase, and the degree of plasma cavity asymmetry as a function of the laser-plasma parameters is calculated.
Polarization control of electron injection and acceleration in the plasma by a self steepening laser pulse
We describe an interplay between two injection mechanism of background electrons into an evolving plasma bubble behind an intense laser pulse: one due to the overall bubble expansion, and another due
Laser-Accelerated, Low-Divergence 15-MeV Quasimonoenergetic Electron Bunches at 1 kHz
We demonstrate laser wakefield acceleration of quasi-monoenergetic electron bunches up to 15 MeV at 1 kHz repetition rate with 2.5 pC charge per bunch and a core with < 7 mrad beam divergence.
A review of recent progress on laser-plasma acceleration at kHz repetition rate
We report on recent progress on laser-plasma acceleration using a low energy and high-repetition rate laser system. Using only few milliJoule laser energy, in conjunction with extremely short pulses
Relativistic electron beams driven by kHz single-cycle light pulses
Laser-plasma acceleration(1,2) is an emerging technique for accelerating electrons to high energies over very short distances. The accelerated electron bunches have femtosecond duration(3,4), making
Production of high-quality electron beams in numerical experiments of laser wakefield acceleration with longitudinal wave breaking
121301-1 In 1998 Bulanov et al. [Phys. Rev. E 58, R5257 (1998)] proposed a novel scheme for the production of high-quality electron beams in laser wakefield acceleration in which a controlled
