TOF spectra for the N(1,1)fast and N(1,1)slow channels from ionization and dissociation of N2 using linearly polarized (a) 68-fs and (b) 45-fs pulses. N(1,1)slow is clearly seen in 68-fs pulses but nearly disappears in 45-fs pulses. (c) Schematic illustration of the formation time sequence of N(1,1)fast and N(1,1)slow.
