The next generation of laser systems are aiming for intensities at which the radiation reaction force must be included in the plasma dynamics. This new parameter regime is termed QED -Plasmas although in reality at present this simply uses the radiation reaction force, non-linear Compton scattering and pair-production rates from standard text, i.e. it is in no way QED research. This talks aims to explain the radiation reaction force and how this is included, via individual photon emission, in modern plasma kinetic codes. The coupling of this, and the associated gamma-ray emission, to collective plasma dynamics opens up the possibility of using high-power lasers as compact gamma-ray sources and in producing pair plasmas. The talk assumes no prior knowledge of laser-plasmas or radiation reaction and ought to be followed by advanced undergraduates and PhD students.
