TL;DR: In this paper, fast electron injection and transport in solid foils irradiated by sub-picosecond-duration laser pulses with peak intensity equal to 4 x 10(20)W/cm(2) was investigated experimentally and via 3D simulations.

TL;DR: In this article, the authors studied the time-integrated spatial coherence of neon-like germanium x-ray laser radiation with a new dispersing coherence diagnostic, by sampling the diverging beam at each lasing wavelength in several directions simultaneously.

TL;DR: In this article, the authors review principles of picosecond CO2 lasers, operating at 10 mu m wavelength, and their applications for strong-field physics research, and illustrate merits of the wavelength scaling from optical to mid-IR region by the examples of ion/proton acceleration.

TL;DR: In this paper, the collective dynamics of ponderomotively-driven electrons in the interaction of an ultraintense laser pulse with a relativistically transparent target is demonstrated experimentally, and the 2D profile of the beam of accelerated electrons is shown to change from an ellipse aligned along the laser polarization direction in the case of limited transparency, to a double-lobe structure aligned perpendicular to it when a significant fraction of the laser pulse co-propagates with the electrons.

TL;DR: In this paper, the transverse filamentation of beams of fast electrons transported in solid targets irradiated by ultraintense (5 × 1020 W cm−2), picosecond laser pulses is investigated experimentally.
