We present experimental results which show a laser polarization-dependent contribution to electron beam pointing jitter in laser wakefield accelerators (LWFAs). We develop a theoretical model for the polarization dependence in terms of the transverse

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), one of the most common spatiotemporal couplings in the laser fo

We present experimental evidence of relativistic electron-cyclotron resonances (RECRs) in the vicinity of the relativistically intense pump laser of a laser wakefield accelerator (LWFA). The effects of the RECRs are visualized by imaging the driven p

We report on the first demonstration of passive all-optical plasma lensing using a two-stage setup. An intense femtosecond laser accelerates electrons in a laser wakefield accelerator (LWFA) to 100 MeV over millimeter length scales. By adding a secon

Shadowgraphy is a technique widely used to diagnose objects or systems in various fields in physics and engineering. In shadowgraphy, an optical beam is deflected by the object and then the intensity modulation is captured on a screen placed some dis

An AlGaInP‐GaInP strained‐layer quantum well laser structure emitting at 670 nm is pumped by a 7–20 keV scanning electron beam. At room temperature, a threshold power density as low as 57 W/mm2 is obtained, which is only 3.8× the value for dio
