An electron density bubble driven in a rarefied uniform plasma by a slowly evolving laser
pulse goes through periods of adiabatically slow expansions and contractions. Bubble …

The electron injection, for the laser wake field accelerator, controlled through the plasma
density inhomogeneity is studied on a basis of analytical estimates and two-and three …

An improved description for nonlinear plasma wakefields with phase velocities near the
speed of light is presented and compared against fully kinetic particle-in-cell simulations …

The quality of electron beams produced from plasma-based accelerators, ie, normalized
brightness and energy spread, has made transformative progress in the past several …

We present the experimentally generated electron bunch from laser-wakefield acceleration
(LWFA) with a charge of 620 pC and a maximum energy up to 0.6 GeV by irradiating 80 TW …

The propagation characteristics of an elliptic-Gaussian beam in non-uniform plasma have
been investigated by taking into account the combined effects of relativistic and …

The effect of laser polarization on the laser wakefield acceleration (LWFA) of electrons has
been investigated in the bubble regime, in particular when assisted by ionization injection …

Laser wakefield acceleration (LWFA) in a gas cell target separating injection and
acceleration section has been investigated to produce high-quality electron beams. A …

We propose to use tightly focused lasers to generate high quality electron beams in laser
wakefield accelerators. In this scheme, the expansion of the laser beam after the focal …

The use of a short-pulse petawatt (PW) laser (τ L< 200 fs, wavelength≈ 1 μm) enables
experimental realization of a self-guided, multi-centimetre-long multi-GeV laser wakefield …
