| 摘 要： | Using the numerical solution of the time-dependent Schr"odingerequation of a one-dimensional model atom in a two-colour laser field,we have investigated the effects of the potential models on coherentcontrol of atomic multiphoton ionization. It is found that thephotoelectron spectra are obviously different for the long-range(Coulomb-like) and short-range (with no excited bound states)potential model atoms, which are produced by two-colour coherentcontrol of atomic multiphoton ionization in a few laser cycles. Ourresults indicate that two-colour coherent control of atomicmultiphoton ionization can be observed in simulations, depending onthe choice of the model potentials.
