ELECTRON ACCELERATION BY A LOCALIZED,HLGH FREQUENCY ELECTRIC FIELD OCDDRRING IN LASER PLASMA

The problem of electron acceleration by a localized,high frequency electric field has been further investigated by using single particle orbit computations and the resonant field. The computational results obtained can give a better explanation to the phenomena observed in experiments and in particle simulations,it indicates that,the Localized field occurring in resonant absorption behaves more Like a travelling wave, and the resonance of the field with electrons in the critical density region can account for the generation of energetic electrons.
