Orientation Dependent Dissociative Ionization of H2_2 in Strong Elliptic Laser Fields: Modification of the release time through molecular orientation

preprint2020arXivOpen access

Abstract

We investigate the photoelectron angular emission distributions obtained by strong field dissociative ionization of H2_2 using cold target recoil ion momentum spectroscopy. In case of employing laser light with an ellipticity close to 0.9 and an intensity of 1.0 ×\times 1014^{14} W/cm2^2, we find that the most probable release-time of the electron does not generally coincide with the time when the laser field maximizes. The release-time is affected by the molecular orientation. In addition, we observe that the width of the release-time distribution depends on molecular orientation. We attribute this observation to the two-center-interference.
