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 report on experimental results on laser-driven proton acceleration using high-intensity laser pulses. We present power law scalings of the maximum proton energy with laser pulse energy and show that the scaling exponent ξ strongly depends on the

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

Experimental results on the acceleration of protons and carbon ions from ultra-thin polymer foils at intensities of up to 6 × 10 ^19 W cm ^−2 are presented revealing quasi-monoenergetic spectral characteristics for different ion species at the sam

We show experimentally that extreme ultraviolet radiation is produced when a laser pulse is Thomson backscattered from sheets of relativistic electrons that are formed at the rear surface of a foil irradiated on its front side with a high-intensity l

In this paper, a new system for improvement of the pulse contrast in CPA laser systems by use of an ultrafast OPA is reviewed together with a scheme to create sub‐picosecond synchronized OPA pump pulses. The scheme is being implemented at the PHELI

We present a terawatt diode‐pumped chirped pulse amplifier using single‐crystalline Yb:CaF2 as the gain medium. A maximum pulse energy of 420 mJ and a repetition rate of 1 Hz was obtained. After recompression, a pulse energy of 197 mJ and a pulse
