| 英文摘要 | We report on a waveform control of enhanced THz radiation along a femtosecond laser filament in air with a high voltage technique. By applying a DC high-voltage electric field from two sharp electrodes in a direction parallel to the laser filament and scanning it along the filament, the longitudinal evolution of amplified THz emission was demonstrated. By changing the position of the pair of electrodes along the laser filament, different waveforms of THz radiation were obtained. Due to the change of the plasma density distribution at the leading and trailing ends of a laser filament, the enhanced THz waveforms could have a phase shift of similar to pi. The technique is very simple. It could help to understand the THz generation process through external electric field assisted laser filamentation. Published by AIP Publishing. |
