Exploring photoelectron angular distributions emitted from molecular dimers by two delayed intense laser pulses

Abstract: We describe the results of experiments and simulations performed with the aim of extending photoelectron spectroscopy with intense laser pulses to the case of molecular compounds. Dimer frame photoelectron angular distributions generated by double ionization of N 2 -N 2 and N 2 -O 2 van der Waals dimers with ultrashort, intense laser pulses are measured using four-body coincidence imaging with a reaction microscope. To study the influence of the first-generated molecular ion on the ionization behavior of the r… Show more

“…Thus, by this procedure the unknown, constant CEP-offset of the experiment is precisely connected to the CEP-value of the simulations. Further information on the few-cycle laser setup and reaction microscope can be found in references [12,23,[53][54][55].…”

“…Instead, the molecular electronic structure is imprinted in the photoelectron momentum distributions. 24–26 This is in contrast to single-photon 27 and multiphoton ionization scenarios 15,28 where the contribution from specific molecular orbitals can be distinguished based on photoelectron energy.…”

“…Instead, the molecular electronic structure is imprinted in the photoelectron momentum distributions. [24][25][26] This is in contrast to single-photon 27 and multiphoton ionization scenarios 15,28 where the contribution from specific molecular orbitals can be distinguished based on photoelectron energy. Therefore, in order to investigate the influence of certain laser pulse parameters on the emergence of the PECD in PADs in the strong-field regime, as is done here, specific experimental techniques need to be applied.…”
