【摘要】 The processes of electric ion extraction from plasma induced by pulse lasers are simulated by particle-in-cell (PIC)method and hybrid-PIC method. A new calculation scheme named preprocessing hybrid-PIC is presented because neither of the two methods above is omnipotent, especially under the circumstance of high initial plasma density. The new scheme provides credible results with less computational consumption than PIC method in both one-and two-dimensional simulations, except forΠ-type electrode configuration. The simulation results show that the M-type performs best in all electrode configurations in both high-density and low-density plasma conditions.
