A laser pulse copropagating with a relativistic plasma wave (wakefield) can experience a continuous upshift in frequency known as “photon acceleration”. Recent particle-in-cell (PIC) simulations have demonstrated how an optical laser pulse can be accelerated to extreme ultraviolet (XUV) frequencies in an electron-beam-driven plasma-wakefield using a tailored plasma density profile. Intense (I0>1017 W/cm2) XUV laser light is highly sought after for collision experiments with multi-GeV electrons; the high photon and electron energy indicates the onset of effects in strong-field quantum electrodynamics, such as non-linear Compton scattering and Breit-Wheeler pair production. By combining PIC simulations of photon acceleration with Monte-Carlo simulations of the electron-photon collision, we show how the brilliance, yield, and polarization of the emitted γ-rays can be optimized for applications in nuclear and particle physics.
