Using the time-dependent wavepacket method and employing the four-state modelthe influence of the laser intensity on the population of the NO molecule electronic states are calculated in this paper. The populations of the electronic states of the NO are given by the wavefunctions obtained by solving the Schrdinger equation through the split-operator Fourier transform method. The calculated results show that different pump pulse intensities have different influences on the population of the electronic states of NO. By changing the pulse intensitythe ionization ratio can be controlledwhich will benefit the light manipulation of atomic and molecular processes.
