Study of Electron Heating Mechanism in Interaction Between Laser Pulse and Plasmas With Steep-density Distribution

  • 摘要: 本文利用二维PIC模拟了超短超强激光与陡峭密度梯度等离子体相互作用过程中电子的加热机制。结果表明,在1023 W/cm2的超短超强激光场与陡峭密度分布的μm级等离子体层相互作用的过程中有质动力加速、大幅度等离子体尾场及共振吸收共同决定了电子束的加速与加热。

     

    Abstract: The electron heating mechanism was studied using PIC simulation in the interaction between the ultra-short ultra-intense laser and the steep-density scale length plasmas. It is found that the ponderomotive acceleration, large amplitude plasma wake field and resonant absorption determine the heating of electrons.
