Abstract
A terahertz light generation devicecomprises a resonator structurefor intensifying incident light and outputting the intensified light and laser oscillation unitsfor feeding the incident light into the resonator structure. The incident light comprises first and second incident light components having polarization states different from each other and frequencies different from each other. The laser oscillation unitsfeed the resonator structurewith the first and second incident light components at an angle inclined from a principal surface in the resonator structure. The resonator structureoutputs light having a frequency corresponding to the difference between the respective frequencies of the first and second incident light components.
