We have shown that even laser pulses having near relativistic intensities can be reflected and up-shifted by relativistic flying mirrors formed by breaking wake waves in underdense plasma. Here we continue this investigation looking at the focusing of the reflected light. We do this with 2D particle-in-cell simulations using the EPOCH code, 国際会議AAPPS-DPP2018への参加}, title = {Focusing and Up-shift of Ultra-high Intensity Lasers Reflected by Relativisitic Flying Mirrors}, year = {2018} }
