We simulate experimental conditions for nonlinear spectral broadening and compression of multi-joule, sub-picosecond, and femtosecond laser systems focusing on 1 μm center wavelength. The spatial, spectral, and temporal properties of two distinct ca

Radiative-shocks induced by laser–cluster interactions are modeled using radiation-hydrodynamic simulations. A good agreement—in both shock velocity and density profiles—is obtained between experiment and simulations, indicating that non-local

Simulations were performed in order to investigate whether the stationary phase point method can be used to estimate the dominance of higher-order dispersion of the optical element under study. It was shown that different higher-order dispersion term

A laser-wakefield driven x-ray source is used for the radiography of human bone. The betatron motion of accelerated electrons generates x-rays which are hard (critical energy keV), have small source size (

A bright μm-sized source of hard synchrotron x-rays (critical energy Ecrit > 30 keV) based on the betatron oscillations of laser wakefield accelerated electrons has been developed. The potential of this source for medical imaging was demonstrated by

Laser-wakefield accelerators, comprising of a high-power laser (> 100 TW) laser pulse incident on a low-density plasma, are a promising compact sources of high-energy electron beams. Recently it was shown that plasma-based accelerators can act as eff

We present numerical and experimental studies on a front-end laser system for seeding a sub-picosecond multi-terawatt/petawatt light source based on two highly saturated optical parametric amplifiers. Numerical results showing energy gain, spectral g

We demonstrate that more stationary phase points appear in the spectral interferogram if the higher‐order dispersion coefficients are dominant. Observing the width and the position of the stationary phase points, the sign and magnitude of the dispe

Pulse front distortion caused by chromatic aberration and coma is studied by the use of spectral interferometry. The spatial‐temporal intensity profile of the pulse is obtained directly from the spectral interferogram using a new, simplified Fourie
