There is the need for high brillance γ-ray sources for fundamental physics applications. Rel-
ativistic flying mirrors generated by ultra-high intensity laser pulses (driver) propagating in
plasma have been used to upshift and focus counter-propagating laser pulses (source) via the
double Doppler effect (see [1] and cited references). Up to now the source laser pulse has been
of sufficiently low intensity so as to not significantly perturb the mirror. We have shown in
particle-in-cell (PIC) simulations that in the case where the source pulse is of high intensity
the boosted harmonics can be generated[2]. In this paper we investigate this using 2D and 3D
PIC simulations where two counter-propagating laser pulses of high intensity, one focusing and
one de-focusing, collide. We will present our considerations for using relativistic flying mirrors
towards achieving high flux γ-ray sources.
