Abstract
Excitation light of two wavelengths is incident to an optical crystal from a first face side, and a terahertz wave THzis generated from a second face, and the excitation light that has passed through the optical crystal is reflected, made incident to the optical crystal from the second face side, and a terahertz wave THzis generated from the first face. Terahertz waves with similar characteristics to each other are thereby generated reliably in plural directions.
