摘      要：The strong-coupling mode,called thequasimode,is excited by stimulated Brillouin scattering(SBS)in high-intensity laser-plasma *** SBS of the quasimode competes with SBS of the fast mode(or slow mode)in multiion species plasmas,thus leading to a low-frequency burst behavior of SBS *** between the quasimode and the ion-acoustic wave(IAW)is an important saturation mechanism of SBS in high-intensity laser-plasma *** results give a clear explanation of the low-frequency periodic burst behavior of SBS and should be considered as a saturation mechanism of SBS in high-intensity laser-plasma interactions.
