  We study the dynamical Schwinger effect in the vacuum excitation of the
electron-positron plasma under action of a "laser pulse" of the simplest
configuration: a linearly polarized, time-dependent and spatially homogeneous
electric field. Methodical basis of this investigation is the kinetic equation
which is an exact consequence of the basic equations of motion of QED in the
considered field model. In the present work we investigate some features of the
residual electron-positron plasma and the transient process of its formation.
