It is accepted that electromagnetic shocks in initially unmagnetized relativistic plasmas are triggered by filamentation instability. However, the transition from the first unstable phase to the quasi-steady shock is still missing. We derive a theoretical model for the shock formation time, taking into account filament merging in the nonlinear phase of the filamentation instability. This process is much slower than in electron-positron pair shocks, and so the shock formation is longer by a factor proportional to root m(i)/m(e) ln (m(i)/m(e)). ER -
