Optica terahertz
WebIn engineering, the terahertz gap is a frequency band in the THz region for which practical technologies for generating and detecting the radiation do not exist. It is defined as 0.1 to 10 THz ( wavelengths of 3 mm to 30 µm) although the upper boundary is somewhat arbitrary and is considered by some sources as 30 THz (a wavelength of 10 µm). [26] WebApr 10, 2024 · where \(\theta \) is the angle between the phase and group fronts of the laser signal. Since ν g is usually greater than c/n T, we can fulfill condition (1) by fitting angle θ.. …
