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.

使用细胞内粒子模拟，我们报告了一种基于阵列激光-等离子体相互作用在等离子体波导的电子密度中生成慢波结构的有效方案。等离子体波导电子密度的空间分布通过有效控制激光器的超高斯指数和阵列图案编码来调制。获得了等离子体波导的电子密度结构的保持时间和可承受的激光强度的完整概述。此外，等离子体波导的慢波结构的保持时间也通过调整阵列激光束的频率来控制。最后，详细讨论了离子运动的影响。
