| Abstract: | A solitary structure of quasi-static electromagnetic pulse is formed in moderate density plasmas by a propagation of ultra-intense
and ultra-short laser pulse, which is formed after the laser pulse is depleted and slowly propagates in the laser propagation
direction. The structure is sustained by huge magnetic pressure and compensating electric field which are in an electromagnetic
equilibrium together with the plasma motion. The solitary structure is formed when the resonance condition is satisfied and
laser intensity is high enough to induce huge magnetic field pressure. |
