摘　　要：Compared with direct ablation,a prepulse is used to propulsion. It is found that the coupling coefficient is beam and the prepulse. At a delay time of 12 ns,the × 10^-5 N/W. enhance the coupling coefficient in laser plasma related with the delay times between the main coupling coefficient reaches the maximum of 5.8
