Title Ultrafast ionization study of N-2 in intense linearly and circularly polarized laser fields
Abstract  A detailed investigation has been carried out of N-2 molecules in intense 55 and 220 fs, linear and circular polarized, 790 nm laser pulses. Using an intensity selective scanning technique, ionization, dissociation, and dissociative ionization channels have been studied. Remarkably similar enhancements of signal with linear polarization observed for double ionization and dissociation channels demonstrate the dominance of dynamic alignment over rescattering effects. Fragmentation energies from dissociative ionization are reasonably well reproduced by classical trajectory calculations, the higher charged fragments displaying evidence of post dissociative ionization.
