Journal ArticleDOI
Direct Measurement of the Electron Density of Extended Femtosecond Laser Pulse-Induced Filaments
TL;DR: Direct time- and space-resolved measurements of the electron density of femtosecond laser pulse-induced plasma filaments show the dominant nonlinearity responsible for extended atmospheric filaments is shown to be field-induced rotation of air molecules.
Journal ArticleDOI
Ultrahigh-Intensity Optical Slow-Wave Structure
TL;DR: The development of corrugated "slow-wave" plasma guiding structures with application to quasiphase-matched direct laser acceleration of charged particles and generation of a wide spectrum of electromagnetic radiation is reported.
Journal ArticleDOI
Trapping and destruction of long-range high-intensity optical filaments by molecular quantum wakes in air.
TL;DR: In a pump-probe experiment, it is found that the probe filament can be sucked into the pump filament's molecular quantum wake and trapped or be destroyed by it.
Journal ArticleDOI
Optical nonlinearity in Ar and N2 near the ionization threshold.
TL;DR: In this article, the nonlinear optical response in argon and nitrogen in a thin gas target to laser intensities near the ionization threshold was measured, and the peak instantaneous index response scales linearly with the laser intensity until the point of ionization, whereupon the response turns abruptly negative and ∼constant.
Journal ArticleDOI

TL;DR: The first measurements of the angular dependence of the betatron x-ray spectrum produced by electrons inside the cavity of a laser-wakefield accelerator are presented, showing strong evidence of anisotropic electron trajectories.
