| 1 | Burst behavior due to the quasimode excited by stimulated Brillouin scattering in high-intensity laser-plasma interactions显示文摘The strong-coupling mode,called the'quasimode',is excited by stimulated Brillouin scattering(SBS)in high-intensity laser-plasma interactions.Also 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 reflectivity.Competition between the quasimode and the ion-acoustic wave(IAW)is an important saturation mechanism of SBS in high-intensity laser-plasma interactions.These 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. | Q.S.Feng L.H.Cao Z.J.Liu C.Y.Zheng X.T.He | 2019 | High Power Laser Science and Engineering2019，7，4： | 0 |
