Abstract
In the past few years, new applications of terahertz wave have given rise to the development of intense terahertz wave source and modulation of terahertz wave [1–4]. However, rigorous experimental conditions or few theoretical explanations were in these works. In this paper, a method to enhance and control the THz pulse generation in air plasma by external electric field is proposed. Two theoretical models, the optics Four-Wave-Mix-Frequency and the electrodynamics electromagnetic radiation are given to explain the results of the proposed method respectively.
