Dissociation and ionization of molecular ions by ultra-short intense laser pulses probed by coincidence 3D momentum imaging

“…Experiments using 45 fs pulses showed KER-spectra in the range of 2-10 eV when the intensity exceeded 1.7×10 14 W/cm 2 [4,11,15]. At lower intensities the dissociation channel dominated completely and no Coulomb explosion was observed.…”

“…The study of bond-stretching during the ionization process has been made possible by enhanced control over pulse duration [4,11] and through pump-probe techniques [12,13,14]. In Ref.…”

Simultaneous 3D coincidence imaging of cationic, anionic, and neutral photo-fragments

“…23,24 Ben-Itzhak and co-workers developed a photofragment spectrometer combined with a fast cation beam for coincidence detection, resolving cationic and neutral dissociation products. [25][26][27] Using a fast anion beam target and a similar concept of an electrostatic spectrometer, we are able to investigate different competing dissociation and electron detachment channels in intense field interaction with atomic, molecular, and cluster anions. [28][29][30][31][32][33] The photofragment spectrometer design allows coincidence detection of all the possible dissociation products on the same detector, including the anionic, cationic, and neutral fragments.…”

Fragmentation ofCD+induced by intense ultrashort laser pulses

“…The ability to perform kinematically complete measurements and identify fragmentation channels unambiguously has deepened our understanding of laser-ion interactions [15,16,[19][20][21][22][23][24][25][26][27][28]. Heteronuclear molecules are an interesting subject for laser fragmentation studies due to their identifiable breakup channels, but they can present additional experimental challenges, especially as the mass ratio between the fragments increases.…”
