Two identical laser pulses impinge from the left and right on a spherical thin-shell plasma. The arrows show the directions of the incident lasers.
Laser energy density distribution at (a) , when the centers of the two CP laser pulses are at the leftmost and rightmost shell surfaces , and (b) , when the highest-intensity regions of the lasers are at the poles . The corresponding ion density is shown in (c) and (d), respectively. The arrows show the directions and relative magnitudes of the velocities of typical ions.
Evolution of the ion density (a) , (b) , (c) , and (d) . A region of high ion density inside the shell cavity can be seen in (c).
(a) Ion energy profile in the x, y plane at T = 48. The color code is in units of MeV. (b) The corresponding electron and ion energy distribution.
