Plasma-based accelerators that impart energy gain as high as several GeV to electrons or
positrons within a few centimeters have engendered a new class of diagnostic techniques …

This is a review of some recent development in femtosecond filamentation science with
emphasis on our collective work. Previously reviewed work in the field will not be discussed …

In its 60 years of existence, the field of nonlinear optics has gained momentum especially
over the past two decades thanks to major breakthroughs in material science and …

Direct Measurement of the Electron Density of Extended Femtosecond Laser Pulse-Induced
Filaments Page 1 Direct Measurement of the Electron Density of Extended Femtosecond Laser …

The absolute time-dependent nonlinear response of O 2, N 2, N 2 O, and Ar to intense
nonionizing, ultrashort optical pump pulses is measured with single-shot spectral …

A new type of microstructured fiber for mid-infrared light is introduced. The chalcogenide
glass-based microporous fiber allows extensive dispersion engineering that enables design …

The propagation of high intensity laser beams is excessively affected by optical nonlinear
effects, thereby the knowledge of the nonlinear refractive indices of the beam guiding media …

We report the first observation of the strong effect of quantum rotational wave packets in
atmospheric air on the long-range filamentary propagation of intense femtosecond laser …

Femtosecond laser-induced alignment and periodic recurrences in hydrogen and deuterium
are measured in a single shot for the first time, in a room temperature gas cell. Single-shot …

We directly measure the nonlinear optical response in argon and nitrogen in a thin gas
target to laser intensities near the ionization threshold. No instantaneous negative nonlinear …
