通过啁啾激光脉冲增强单色成丝过程中的太赫兹发射

Enhancement of terahertz emission during single-color filamentation by chirping laser pulse

Georgy Rizaev, Dmitrii Pushkarev, Maximilian Levus, Nadezhda Vrublevskaya, Leonid Seleznev

AI总结:

本文实验研究了激光脉冲啁啾对单色成丝太赫兹发射的影响,发现每个太赫兹频率存在最优脉冲持续时间,且更长脉冲可将太赫兹辐射产额提高超过3倍。

摘要:

本文开展了一项关于激光脉冲持续时间对单色成丝过程中太赫兹发射影响的实验研究。研究表明,对于每个太赫兹频率,在脉冲能量恒定的条件下,存在一个能够提供最大太赫兹产生效率的最优激光脉冲持续时间。实验证明,更强的低频太赫兹发射需要更长的激光脉冲,因此尽管激光峰值功率显著降低,太赫兹辐射产额仍可提高超过3倍。

英文摘要:

An experimental study of laser pulse duration influence on the terahertz emission during single-color filamentation is carried out. It is shown that for each terahertz frequency there is an optimal laser pulse duration providing maximal generation at constant pulse energy. It is demonstrated that longer pulses are required for stronger low-frequency terahertz emission, thus despite considerable laser peak power decreasing the terahertz radiation yield can be increased by more than 3 times.
