摘要： The laser pulse shape effect and mainly the stepout effect on the ionization are investigated numerically in this paper. About the pulse shape effect, the result shows that it would be better to use shorter Gaussian pulses on the condition of constant area. About the stepout problem, the calculation shows that a certain stepout between pulses will benefit the ionization. Some interesting phenomena caused by stepout among pulses are found and explained in population dynamics.
