Terahertz waves are electromagnetic waves with frequencies between roughly 0.1 and 10 THz (T = tera (1012<\/sup>)). In the past, there were no bright light sources or easy to use detectors for this frequency band, making generation and detection difficult. Because of this, despite the fact that various types of elementary excitation occur within the terahertz region, such as phonons, low-dimensional plasmons, and cyclotron resonance, these phenomena were not understood in depth. In order to solve this problem, the group engages in:
\n1. Development of terahertz wave generation, detection, and spectroscopy methods using various lasers
\n2. Solid state physics, biophysics, and physical chemistry research using terahertz wave spectroscopy and development of nondestructive inspection methods using terahertz waves<\/p>\n
