Paper Abstract

The generation of terahertz (THz) wave from a single-color femtosecond (fs) laser-induced air plasma with a dc biased field is studied. A systemic investigations of the THz wave polarization by changing the direction of dc biased field in parallel or perpendicular to pump pulse polarization. The results demonstrate that the THz wave generation is the sum of ponderomotive force and the dc biased field, and the external dc biased field can amplify and modulate the total THz waveform.
