On the complex momentum spectra of photoelectrons formed from H2 in a strong laser field

Strong Field Phenomena

Abstract

We have experimentally investigated the ionization of molecular hydrogen in a strong, linearly polarized laser field. The angularly-resolved photoelectron spectra of H2 were determined as a function of laser intensity at 800 nm, using pulses of 100 fs duration. A substantial portion of the molecular photoelectron spectra mimics those of atomic hydrogen. We provide qualitative interpretations for this and other features in the spectra. The very high resolution of our data will pose a stringent test on the validity of strong-field theories.
