Abstract

Ab initio simulation of the interaction of a temporally short and intense circularly polarized laser pulse with an aligned benzene molecule was performed. Focus was on the two processes in this system, ionization and HHG yields. As for ionization, it was found that for field strengths larger than 1X10¹⁴W cm^-1, the intensity is sufficiently strong so that the electrons pulled out of the molecule do not return to it. For strong fields, ionization ceases well before the pulse reaches maximum, while for pulses of maximal strength smaller than 1X10¹⁴ W cm^-2 the ionization continues throughout.
