摘要

提出了一种利用超短强激光脉冲入射薄板产生单周期强太赫兹(THz)脉冲的新方案。我们的理论模型表明，如果τL >2π/ωp，τL为激光脉冲持续时间，ωp为等离子体频率，则发射频率在τL−1附近。

Single-cycle powerful terahertz pulse generation from vacuum-plasma interface driven by intense laser pulses

A new scheme to generate single-cycle strong terahertz (THz) pulses by ultrashort intense laser pulses incident onto a tenuous plasma slab is proposed. Our theory model suggests that, if τL >2π/ωp with τL the laser pulse duration and ωp the plasma frequency, the emission frequency is around τL⁻¹.
