摘要
超短激光脉冲驱动等离子体光丝产生太赫兹辐射的研究对于揭示太赫兹产生的微观机理以及太赫兹源的发展和应用有重要的基础意义。系统介绍了包括载波包络稳定的红外周期量级激光脉冲的产生、基于周期量级激光强场驱动等离子体光丝产生太赫兹辐射的机理、等离子体光丝中周期量级光场的传输、波形可控太赫兹辐射的产生及其在载波包络相位测量技术上的应用等方面的最新进展。
Abstract
Terahertz (THz) emission from plasma filament driven by ultra-short laser pulses attracts intense interests for revealing the microscopic dynamics of THz generation and providing new THz sources for applications. This review covers the recent progress in the areas including: the generation of carrier envelope phase (CEP) stabilized infrared (IR) few-cycle laser pulses, the models of THz generation from plasma filament by intense few-cycle laser field, the propagation of few-cycle laser pulses in air plasma, the waveform controlled THz emission and its application in the measurement of actual value of CEP.
