We investigate the electron dynamic process of a one-dimensional two-electron atom irradiated by strong laser pulse using the improved time-dependent quantum Monte Carlo (TDQMC) scheme. By comparison with the scheme for solving the time-dependent Schrdinger equation by using the accurate numerical integration, the dynamic variation of particle in a quantum ensemble, corresponding to the calculated wave-packet, is consistent with the evolution of time-dependent wavepacket. The computation efficiency of the TDQMC is more largely enhanced than that of the time-dependent integration method. According to the dynamic evolution behaviors of the calculated classical particle ensemble, we analyze the excitation, ionization, recombination of electron and other non-linear processes in a strong laser field.
