TERAHERTZ WAVE GENERATOR AND METHOD OF GENERATING TERAHERTZ WAVE

摘要

PURPOSE: A terahertz wave generator and a generating method thereof are provided to operate a light source or a photo mixer in a wavelength having an optimum reliability, and to improve a controlling range of frequency. CONSTITUTION: A terahertz generator comprises: a first light source (210), a second light source (220), a secondary high frequency generating unit (230), and a photo mixer (240). The first light source outputs a first light having a first frequency. The second light source outputs a second light having a second frequency which is different from the first frequency. The secondary high frequency generating unit produces a third light and a fourth light by converting the first and second light respectively. The photo mixer converts the mixed light of third and fourth light into terahertz wave alternating current, and outputs the terahertz wave.
