摘要：
As an intense, nonuniform ultrashort laser pulse strikes the overdense plasma, the electron mass increases and electron beam frequency decreases due to relativistic effect. A laser wave can penetrate the plasma more deeply. When laser beam is nonuniform, a channel forms as a result of strong ponderomotive force, which is shown by 2-D particle simulation.
