WA3.3 - MEGAFILAMENTATION OF TERAWATT, LONG-WAVELENGTH INFRARED LASER PULSES IN AIR

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.
