Terahertz radiation from a laser plasma filament

Author(s): H.-C. Wu (武慧春), J. Meyer-ter-Vehn, H. Ruhl, and Z.-M. Sheng ( 盛政明)
By the use of two-dimensional particle-in-cell simulations, we clarify the terahertz (THz) radiation mechanism from a plasma filament formed by an intense femtosecond laser pulse. The nonuniform plasma density of the filament leads to a net radiating current for THz radiation. This current is mainly...
