Particle dynamics and radiation in an ultra-intense standing wave
Original language description
As 10 PW laser facilities are now being built, more attention is paid to studying interactions at ultra-relativistic laser intensities of the order of 10^23 - 10^24 W/cm2. Such a high laser intensity will allow to enter the quantum dominated regime of the interaction in which prolific pair production via Breit-Wheeler process may occur. Therefore, possible future interaction scenarios leading to prolific gamma-ray emission and pair production in a strong electromagnetic field are studied now, such as interaction of charged particles with two or more counter-propagating laser beams. Using 2D PIC simulations we studied photon emission and pair production in the standing wave produced by two focused colliding laser pulses interacting with a target in their common focal spot. The influence of target density, thickness and ions on gamma-ray generation and pair creation is assessed for both laser polarization. While ions do not play an important role for photon emission and pair production in the case of circular polarization, they affect electron dynamics in the standing wave when linear polarization is used that leads to more efficient pair production. The efficiency is also subject to properly picked target thickness and density with respect to a laser intensity.
