Simulation of EM wave propagation along a femtosecond laser plasma filament
Abstract
The propagation of electromagnetic (EM) wave along a plasma filament induced by the sufficiently intense femtosecond laser pulse is studied with the commercial simulation software XFDTD. The simulated results show that the EM wave can propagate along the plasma filament, with the electric field enhanced out of the waveguide and attenuated in the waveguide. Besides, we can conclude that the relative direction between the plasma filament and the electric field can influence the guiding performance of the plasma filament. Furthermore, a maximum EM wave intensity enhancement more than threefold the free space propagation is realized. The research results imply that the laser-induced plasma filament can provide efficient transmission of the EM wave energy.
