Plasma-Wave Interaction

Formation and Evolution of Electromagnetic Solitons

Formation and evolution of electromagnetic solitons have been investigated by relativistic electromagnetic Particle-in-Cell simulations. Injection of a strong electromagnetic wave into an underdense low density plasma layer causes stimulated Raman scattering, Raman cascade into Photon condensation, and forma-tion of an electromagnetic soliton. A relativis-tic soliton formed in the left hand side of the plasma layer grows and is decelerated and finally propagates in the backward direction.
