Abstract
The nonlinear polarization response and plasma generation in noble gases produced by high- intensity optical pulses, modeled by the metastable electronic state approach, are verified against three-dimensional, space-and-time resolved measurements with single-shot supercontinuum spectral interferometry. This first of a kind theory-experiment comparison is done in the intensity regime typical for optical filamentation, where both self-focusing and plasma generation play competing roles. Finding an excellent agreement between the theory and experiment for three noble gases allows us to refine the post-adiabatic model corrections describing wavelength-dependent effects.Citation
