英文摘要	the influence of laser-field parameters, such as intensity and pulse width, on the population of molecular excited state is investigated by using the time-dependent wavepacket method. for a two-state system in intense laser fields, the populations in the upper and lower states are given by the wavefunctions obtained by solving the schrodinger equation through split-operator scheme. the calculation shows that both the laser intensity and the pulse width have a strong effect on the population in molecular excited state, and that as the common feature of light-matter interaction (lmi), the periodic changing of the population with the evolution time in each state can be interpreted by rabi oscillation and area-theorem. the results illustrate that by controlling these two parameters, the needed population in excited state of interest can be obtained, which provides the foundation of light manipulation of molecular processes.
