Characterization of light-induced potentials in the strong-field dissociation of O₂⁺

We examine the imprints of light-induced potentials (LIPs) on the dissociation dynamics of O₂⁺ molecular ions, as observed in the angle-resolved fragment kinetic-energy-release (KER) spectra. By numerically solving the time-dependent Schrödinger equation within the Born-Oppenheimer approximation, we follow the vibrational and rotational motion of O₂⁺ molecular ions exposed to 800-nm, 40-fs laser pulses. For peak intensities between 10¹³ and 10¹⁴ W/cm², we calculate angle-resolved KER spectra which reveal characteristic energy- and angle-dependent fringe structures associated with the LIPs.
