We used pump-probe technique with few-cycle pulses and COLTRIMS
detection to
study dynamics of ionization and dissociation of molecules following
ionization/excitation by a strong field of ultra-short laser
pulse. We
detected in coincidence pairs of H$^{+}$ ions and single and
multiple
charged ions of nitrogen N$^{q+}$ produced by pump and probe
pulses in
ionization and dissociation processes. Setting the delay between
the two
pulses we measured the kinetic energy release dependence on the
delay time,
which vibrational and dissociative dynamics. We were able to
follow the
contribution of each separate channel to the total ions yield at
each delay.
