basic information
**Lecture Summary** In recent years, the development of light sources in the electromagnetic frequency range known as terahertz waves, approximately 0.3 to 10 THz (wavelength 1 mm to 30 μm), and the exploration of their applications have been rapidly advancing. This range is positioned between radio waves and light waves, allowing it to penetrate various materials such as paper, plastic, vinyl, fibers, semiconductors, and powders like radio waves, while also being manipulable in space using lenses and mirrors like light waves. Additionally, due to its shorter wavelength compared to millimeter waves, it possesses sufficient spatial resolution for many imaging applications. Furthermore, in recent years, unique absorption spectra specific to reagents such as vitamins, sugars, pharmaceuticals, and explosives have been discovered in the terahertz range, expanding its potential applications. We are energetically advancing the development of a broadband wavelength-tunable terahertz light source using nonlinear optical effects, as well as the application development of terahertz waves, and have been highly regarded internationally, including over 100 invited talks at international conferences in the past decade. I will provide an intensive explanation of these fundamental technologies.
