Abstract
Abstract
A new regime of laser filamentation is demonstrated with terawatt, picosecond CO2 laser pulses forming a single centimeter diameter channel in air. Joules of pulse energy are self-guided at a clamped intensity of ~1012 W/cm2 due to generation of free carriers via many-body Coulomb effects.

Abstract
Abstract
Numerical modeling of polycrystalline transparent materials exhibiting strong supercontinuum
and high-harmonic generation is challenging due to the random nature of these media. This paper describes
modeling approaches suitable for realistic simulation of extreme nonlinear optics in such materials.
