Laser-induced dissociative recombination of carbon dioxide

Abstract

We experimentally investigate laser-induced dissociative recombination of CO2 in linearly polarized strong laser fields with coincidence measurements. Our results show laser-induced dissociative processes with electron recombination after laser-induced double ionization. After double ionization, one electron can recombine to one of the two ionic fragments during laser-induced molecular dissociation. Our measurements reveal that the recombination probability of the second ionized electron is three times as high as that of the first ionized electron.
