Conical Forward THz Emission from Femtosecond-Laser-Beam Filamentation in Air

Résumé

We attribute a strong forward directed THz emission from femtosecond laser filaments in air to a transition-Cherenkov emission from the plasma space charge moving behind the ionization front at light velocity. Distant targets can be easily irradiated by this new source of THz radiation.
