The terahertz (THz) portion of the electromagnetic spectrum, lying above the frequencies of electronics (>0.1 THz) and below those of photonics (< 30 THz), represents the last frontier of the commercial applications of light. A multitude of applications are possible with these THz pulses. However, there are several characteristics of THz radiation that are holding back its widespread applications in industry. First, THz radiation is highly absorptive to polar liquids, such as water, thus making it difficult for applications involving most aqueous media. Secondly, THz absorption spectra are complicated even for pure materials, and thus conventional THz spectroscopy rapidly loses its effectiveness for identifying complex mixtures, which is what one frequently faces in the real world.

电磁频谱的太赫兹(THz)部分高于电子学的频率(&gt；0.1太赫兹)，低于光子学的频率(&lt；30太赫兹)，代表了光商业应用的最后前沿。利用这些太赫兹脉冲可以实现多种应用。然而，太赫兹辐射的几个特点阻碍了其在工业上的广泛应用。首先，太赫兹辐射对水等极性液体具有很强的吸收能力，因此很难应用于大多数含水介质。其次，即使对于纯物质，太赫兹吸收光谱也很复杂，因此传统的太赫兹光谱很快就失去了识别复杂混合物的有效性，这是人们在现实世界中经常面临的问题。
