Paper Abstract

Because the efficiency of THz generation in air plasma is quite low, the residual power of input beam after THz radiation is generated in air plasma remains almost the same. A new method, multiple air plasmas, is proposed. The residual power can be used to induce other air plasmas and generate THz radiation again. The multiple air plasmas method provides a potential way for the development of the intense THz source. The preliminary experimental results confirm the theoretical prediction. The multiple air plasmas generated THz can be very useful for remote THz generation and standoff detection.
