Preface The critical electric field of quantum electrodynamics, called also the Schwinger field, is so strong that it produces electron-positron pairs from vacuum, converting the energy of light into matter. Since the dawn of quantum electrodynamics there has been a dream on how to reach it on Earth. With the rise of the laser technologies this field becomes feasible through construction of extreme power lasers or with the sophisticated usage of nonlinear processes in relativistic plasmas. Recently there were raised doubts on whether or not the Schwinger field can be reached with lasers. It was claimed that the laser with intensity well below the Schwinger limit creates an avalanche of electron-positron pairs similar to a discharge, and the focused laser pulse exhausts its energy before attaining the Schwinger field. This reasoning weakens one of the most attractive motivations for extreme power laser development, i.e. producing matter from vacuum by pure light in fundamental process of quantum electrodynamics in the nonperturbative regime. •A.
