WAVEBREAKING DUE TO RESONANT ABSORPTION IN PLASMAS PRODUCED BY LASER BEAM
激光等离子体共振吸收的波碎过程

Wavebreaking due to resonant absorption in plasmas produced by the laser beam is studied using theoretical analysis and particle simulation of plasma.The temperature effects on wavebreaking and resonant absorption are also considered.It is indicated that those electrons in the resonant region are not only oscillating heated,but also accelarated by Landau damping.There exists a turbulence accelaration mechanism in underdense plasma region.Second wavebreaking can also be observed in certain power density of laser light.
