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 …

In this work, we perform particle-in-cell simulations to investigate the electron bunch quality
using a chirped laser pulse in a laser wakefield acceleration mechanism. Particular attention …

Ultrafast laser pulses featuring both high spatio-temporal beam quality and excellent energy
stability are crucial for many applications. Here, we present a seed laser with high beam …

The simultaneous laser-driven acceleration and angular manipulation of the fast electron
beam are experimentally demonstrated. The bunch of multi-MeV energy charged particles is …

Driving laser wakefield acceleration with extremely short, near single-cycle laser pulses is
crucial to the realization of an electron source that can operate at kHz-repetition rate while …

Guided wave optics, including most prominently fiber optics and integrated photonics, very
often considers only one or very few spatial modes of the waveguides. Despite being known …

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 …

Using a Dazzler system and tilting a compressor grating, we provide an effective way of
using the laser group delay dispersion to continuously steer the electron beam accelerated …

In ultra-short laser pulses, small changes in dispersion properties before the final focusing
mirror can lead to severe pulse distortions around the focus and therefore to very different …

A high-intensity laser pulse propagating through underdense plasma is prone to parametric
instabilities. We report on experiments investigating the influence of a pulse-front tilt (PFT) …
