Relativistic mirrors can be realized with strongly nonlinear Langmuir waves excited by intense laser pulses in underdense plasma. On reflection from the relativistic mirror the incident light affects the mirror motion. The corresponding recoil effects are investigated analytically and with particle-in-cell simulations. It is found that if the fluence of the incident electromagnetic wave exceeds a certain threshold, the relativistic mirror undergoes a significant back reaction and splits into multiple electron layers. The reflection coefficient of the relativistic mirror as well as the factors of electric field amplification and frequency upshift of the electromagnetic wave are obtained.

反冲对激光等离子体中相对论反射镜反射的影响

相对论性反射镜可以通过由低密度等离子体中的强激光脉冲激发的强非线性朗缪尔波来实现。在从相对论镜反射时，入射光会影响镜面运动。相应的反冲效应进行了分析和细胞内粒子模拟研究。研究发现，如果入射电磁波的通量超过某个阈值，相对论镜就会发生显着的反向反应并分裂成多个电子层。得到了相对论镜的反射系数以及电磁波的电场放大和频率上移的因素。
