Terahertz (THz) radiation, which is electromagnetic radiation in a frequency interval from 0.3 to 10 THz (1 mm – 30 μm wavelength), is the frontier in science and technology. Historically, THz technologies were used mainly within the astronomy community for studying the background of cosmic far-infrared radiation, and by the laser-fusion community for the diagnostics of plasmas. Since the first demonstration of THz wave time-domain spectroscopy in the late 1980’s, there has been a series of significant advances (particularly in recent years) as more intense THz sources and higher sensitivity detectors provide new opportunities for understanding the basic science in the THz frequency range.
There are many new technologies which have been developed in this field since the first pulsed THz time-domain spectroscopic system was invented over 30 years ago. Benefiting from those novel technologies, researchers have gradually revealed the unique properties and promising applications of THz waves. I will systematically introduce the various sciences, technologies, and applications of THz waves, with a particular focus on the new challenges and opportunities in the pulsed THz technologies.
