✦ Synopsis

Modern lasers are yet unable to cause
electron-positron pair production in vacuum, however it is
possible to notice considerable influence of vacuum polarization
on radiation that propagates in such medium. The field strength of
modern lasers is not strong enough for creation of
electron-positron pair in a vacuum, but the powerful laser beams
generates polarization of vacuum which can be established
experimentally. In the framework of QED a nonlocal theory of
interaction of intensive laser radiation with electron-positron
vacuum is developed. Refusing from the Heisenberg-Euler
approximation it appears to be possible to calculate non-zero
response of vacuum even for a plane wave. It is described by
corrections to the Maxwell equations obtained by means of the
proper time method. Effects generated by this correction for
propagation of wave are analyzed.
