Abstract

Provided is a terahertz wave apparatus. The terahertz wave apparatus includes: a wavelength-fixed laser emitting a first laser light having a fixed first wavelength; a wavelength-swept laser emitting a second laser light having a tunable second wavelength; a coupler coupling the first laser light with the second laser light; and a generator converting a mixed light emitted from the coupler into a terahertz wave, wherein a frequency of the terahertz wave is continuously tunable.
