In inertial confinement fusion, the laser–plasma interaction (LPI) happens when the high-energy laser irradi-ates on the target where the scattered light share generated from the stimulated Raman scattering (SRS) effect is difficult to suppress. We propose a method using fence pulses (FPs) to suppress the backward SRS by inhibiting the growth of the intensity of electron plasma waves. Based on our simulation, the FPs can weaken SRS effect in the LPI effectively.
