Laser-wakefield accelerators (LWFAs) were proposed more than three decades ago, and
while they promise to deliver compact, high energy particle accelerators, they will also …

The temporal characterization of ultrafast laser pulses has become a cornerstone capability
of ultrafast optics laboratories and is routine both for optimizing laser pulse duration and …

Multi-GeV electron beams with energy up to 4.2 GeV, 6% rms energy spread, 6 pC charge,
and 0.3 mrad rms divergence have been produced from a 9-cm-long capillary discharge …

We report on the generation of a narrow divergence (θ γ< 2.5 mrad), multi-MeV (E max≈ 18
MeV) and ultrahigh peak brilliance (> 1.8× 10 20 photons s-1 mm-2 mrad-2 0.1% BW) γ-ray …

Laser wakefield acceleration of electrons holds great promise for producing ultracompact
stages of GeV scale, high-quality electron beams for applications such as x-ray free electron …

A laser system producing controllable and stable pulses with high power and ultrashort
duration at high repetition rate is a key component of a high energy laser-plasma accelerator …

Experiments were performed on laser wakefield acceleration in the highly nonlinear regime.
With laser powers P< 250 TW and using an initial spot size larger than the matched spot size …

X-ray phase-contrast imaging has recently led to a revolution in resolving power and tissue
contrast in biomedical imaging, microscopy and materials science. The necessary high …

Optimizing the laser wakefield accelerator (LWFA) requires control of the intense driving
laser pulse and its stable propagation. This is usually challenging because of mode …

We describe a simple scheme, truncated-channel injection, to inject electrons directly into
the wakefield driven by a high-intensity laser pulse guided in an all-optical plasma channel …
