The terahertz (THz) region of the electromagnetic spectrum is located between the microwave and infrared regions, with frequencies ranging from 0.1 to 10 THz and corresponding wavelengths between 3mm and 30μm. This region, commonly referred to as the "terahertz gap", has historically been underutilized due to a lack of strong emitters and detectors. However, recent advances in ultrafast laser technologies and electronic device miniaturization have enabled the development of terahertz time-domain spectroscopy (THz-TDS) systems capable of harnessing the unique properties of terahertz radiation.

THz-TDS Systems and Applications

Terahertz Technologies utilizes ultrafast laser pulses to generate and detect coherent broadband terahertz pulses. A femtosecond laser produces pulses that are split - one drives a photoconductive antenna to emit terahertz radiation, while the other acts as a probe to sample the emitted electric field via free-space electro-optic sampling in a detector crystal. By varying the time delay between pulse arrivals, the full terahertz waveform can be reconstructed, enabling the extraction of spectral information via Fourier transform. This technique allows for non-contact, non-destructive identification of materials via their unique terahertz absorptive fingerprint. A wide range of applications are emerging within the biomedical, pharmaceutical, security, and semiconductor industries.
