【Abstract】 It reports the quantitative calculation results of the dissociaton momentum spectra of the three low excited states 1Σ u,2Σ g,2Σ g of the ion Na + 2 in the two pulsed laser fields of wavelength 680nm and intensity 1×10 12 W/cm 2 at different delay times (0,50,100,...,350fs) and different relative phases.Both of the pulse widths are 50fs.The results in the presented table show that the one photon and three photon dissociation peak values depend on the relative phase and the effects decreases with the increasing delay time.更多还原
