Abstract

Summary form only given. To surpass the limitations of previous ultrafast ionization studies and achieve a quantitative measure of the ionization rate independent of probe structure, we have utilized an experiment configuration which, by utilizing three power-spectra channels and one optically gated frequency-resolved channel per each of four CCD images (pumped and unpumped cases with one or two probe pulses), provides simultaneous and self-consistent dual-channel power spectra and frequency domain interferograms, MI-FROG and FROG data.
