摘要: The modification of photon frequency shifting based on taking into account the nonlinear quantum electrodynamics vacuum properties in plasma is studied. Motion equations a laser field propagating are derived from Heisenberg-Euler Lagrangian density. It found that besides classical density perturbation electrons, energy will induce via ponderomotive force vacuum. In addition it shown electron be suppressed, which attributed to screening effect electrons polarization.
