Strong-field QED processes in intense laser fields are presently of great interest in view of upcoming high-intensity laser facilities such as ELI. In this talk I will present recent results of our group on strong-field QED processes such as high-intensity one- and two-photon Compton scattering [1,2] as well as the cross channel pair production processes [3]. These processes are described using QED in the Furry picture with laser dressed Volkov states. The effects of the short laser pulse length of a few tens of femtoseconds are discussed. Furthermore, results for the dynamical Schwinger effect in time dependent electric fields as well as the modification weak interaction processes in intense laser fields are presented [4].
