The development of laser technologies promises very rapid growth of laser intensities in close future already. Two exawatt class facilities (ELI and XCELS, Russia) in Europe are already in the planning stage. Realization of these projects will make available a laser of intensity ~10^26 W/cm^2 or even higher. Therefore discussion of nonlinear optical effects in vacuum are becoming urgent for...

Electron-positron pair production by an incident high-energy photon or a relativistic proton colliding with an intense laser field is considered. Our focus lies on the role played by the electron spin degree of freedom. A comparative study between production of Dirac versus Klein-Gordon pairs is performed [1,2] and a helicity analysis is carried out [3].
