Optical probing is an indispensable tool in research and development. In fact, it has always
been the most natural way for humankind to explore nature. However, objects consisting of …

The choice of the correct density profile is crucial in laser wakefield acceleration. In this
work, both subsonic and supersonic gas targets are characterized by means of fluid …

Accelerating relativistic mirrors have long been recognized as viable settings where the
physics mimic those of the black hole Hawking radiation. In 2017, Chen and Mourou …

A new optical probing method with increased interferometric sensitivity for a low-density gas
jet characterization is presented. The proposed technique employs a Michelson …

Density transition injection is an effective technique for controllably loading electrons into a
trapped phase for laser plasma accelerators. One common technique to achieve the …

Implementation of laser-plasma-based acceleration stages in user-oriented facilities

Supersonic gas-jet target performs an important role in laser wakefield acceleration, and its
density diagnosis is a significant part of target characteristic study. In this paper, a Mach …

Three main paths are being developed within the ELI research program for transforming
driving laser pulses into bursts of bright short wavelength radiation: high-order harmonic …

Wollaston phase-grating interferometer is introduced to measure of the optical phase across
various samples. The system employs a Wollaston prism to create two angularly separated …

Similarly to laser or x-ray beams, the interaction of sufficiently intense particle beams with
neutral gases will result in the creation of plasma. In contrast to photon-based ionization, the …
