In this paper, generated terahertz from filament in air has been considered by generalization of the Cherenkov radiation model and also numerical calculations related to THz radiation behavior which influenced by effect of chirp and pulse duration of initial ultra-short pulse have been done. Therefore, what is observed in the previous experimental works is justified and the cause of phenomenon is expressed.
Keywords: chirp, filamentation, pulse duration, terahertz, ultra-short pulse
