Paper Abstract

Electron-positron pair creation by the electromagnetic wave propagating in plasma is investigated in the reference frame moving with the group velocity of the wave. We derive the exact collisionless kinetic equation with non- Markovian source term for the uniform electric field of arbitrary polarization. The back-reaction of plasma is taken into account by means of the dispersion equation. The time dependence of plasma density is studied for the case of linearly polarized field and intensity characteristic for modern optical and planned X-ray lasers. We found that mean pair density created by linearly polarized wave with amplitude Em less than or equal to Ecr negligible in comparison to initial plasma density.
