Abstract
Large amount of energetic electrons generated in laser wake fields driven by multiparallel laser pulses is investigated with three-dimensional particle-in-cell simulations. By adjusting the distance between the pulses, bubbles with different structure are formed, which results in different injection efficiency. Compared with the single-pulse case, the charge of the energetic electrons could be doubled when the distance between the two pulses is large enough. A characteristic distance between the pulses is obtained, above which the total amount of the energetic electrons increases linearly by applying more laser pulses. There is no limit for the charge increase in our scheme as long as the plasma is wide enough so that more pulses can be applied.
