In this work, using three-state model and time-dependent wave packet method, the wave packet dynamic process and time-resolved photoelectron spectrum of NaLi molecule in femtosecond pump-probe intense laser field are investigated and the relation between the parameter of the femtosecond laser and time-resolved photoelectron spectrum is obtained. It is found that the vibrational periods of wave packet are different for different laser wavelengths and the photoelectron spectra are different for different pump-probe delay times. The height and position of the peak of the photoelectron spectrum change with pump-probe delay time. When 1=352 nm and t=400 fs, the corresponding signal in the outer well (0.5 eV) is obviously smaller than that in the inner well (1.35 eV). The result reveals that the time-resolved photoelectron spectrum reflects the information about the wave packet dynamic of the excited state 41+ The results may be useful for realizing the optical control of molecule and the process of quantum manipulation of molecule experimentally, and provide some important basis for further theoretical research in this respect.
