Abstract
Filamentation characteristics of tightly focused 45 fs laser pulses in air are investigated using transverse imaging in the power range of 20 - 200 GW. The effect of linear and circular polarized light pulses on the onset and spatial evolution of filamentary substructures and the associated supercontinnum emission is studied. © CLEO Pacific Rim 2007.
