摘　　要：Using the particle-in-cell simulations,we report an efficient scheme to generate a slow wave structure in the electron density of a plasma waveguide,based on the array laser-plasma interaction.The spatial distribution of the electron density of the plasma waveguide is modulated via effective control of the super-Gaussian index and array pattern code of the lasers.A complete overview of the holding time,and the bearable laser’s intensity of the electron density structure of the plasma waveguide,is obtained.In addition,the holding time of the slow wave structure of the plasma waveguide is also controlled by adjusting the frequency of the array laser beam.Finally,effects due to ion motion are discussed in detail.
