摘要

We study the effect of laser pulse shape on the plasma wake field driven by an intense laser beam. It is found that the modified asymmetric laser pulse shape with a sharply rising front and broad falling back, due to some nonlinear interactions of an intense laser pulse with plasmas, can significantly enhance the magnitude of the wake field.
