We study the generation of intense terahertz pulses produced by two-color laser pulse filamentation in air. We tailor the filamentation process and the produced plasma strings and study how the generated terahertz field is modified. An important terahertz pulse shortening is found for plasma strings with uniform electron density.
我们研究了空气中双色激光脉冲丝状化产生强太赫兹脉冲的过程。我们调整丝状化过程和所产生的等离子体串，并研究所产生的太赫兹场是如何被改变的。对于具有均匀电子密度的等离子体串，发现了一种重要的太赫兹脉冲缩短现象。
