Density distributions of (a–c), (g−i) electrons and (d−f) (j−l) proton layers driven by Gaussian lasers and LG lasers at t = 60 T, 120 T, and 240 T, respectively. Magnetic field distributions at t = 180 T driven by (m) LG and (n) Gaussian laser, the proton trajectories are shown in the respective insets. Electric field distributions are plot at t = 60 T for (o) LG and (p) Gaussian lasers. q Electron trajectories in the magnetic field in the calculation.
