摘要

太赫兹时域光谱技术是用于化学分析的重要技术手段,然而现有的太赫兹时域光谱技术通常所能探测到的太赫兹频带仅仅在0.1～3THz,这远远无法满足当今世界对化学分析的要求。本实验室搭建了一种全新的基于激光等离子体宽频太赫兹辐射源的太赫兹时域光谱系统,该系统的有效探测带宽为0.1～15 THz,可获得化学物质的更为丰富的光谱信息,为现有化学分析技术提供了一种补充手段。
        Terahertz(THz)time-domain spectroscopy technology is an important technique for chemical analysis. However, the THz band that can be detected by current THz time domain spectroscopy(THz-TDS) system is only in 0.1～3 THz, which is far from meeting the requirements for chemical analysis. Based on laser plasmas broadband THz source, we built a new THz-TDS system with an effective detection bandwidth of 0.1～15 THz, which provides an effective means for chemical analysis.
