Visualization of High-Intensity Laser–Matter Interactions in Virtual Reality and Web Browser Open
We present the Virtual Beamline (VBL) application, an interactive web-based platform for visualizing high-intensity laser–matter interactions using particle-in-cell (PIC) simulations, with future potential for experimental data visualizati…

Collimated <i>γ</i>-flash emission along the target surface irradiated by a laser at non-grazing incidence Open
The interaction of a high-power laser with a solid target provides ways to produce beams of γ -photons. For normal incidence of the laser on the target the beams usually appear in a form of two lobes, which are symmetric with respect to th…

Ultrarelativistic electron beams accelerated by terawatt scalable kHz laser Open
We show the laser-driven acceleration of unprecedented, collimated (2 mrad divergence), and quasi-monoenergetic (25% energy spread) electron beams with energy up to 50 MeV at 1 kHz repetition rate. The laser driver is a multi-cycle (15 fs)…
