Abstract
Excitation light of two wavelengths is incident to an optical crystal from a first face side, and a terahertz wave THzb is 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 THza is generated from the first face. Terahertz waves with similar characteristics to each other are thereby generated reliably in plural directions.
Claims15
A terahertz wave generator comprising:
- a nonlinear optical crystal that is disposed on an optical path of excitation light containing light with a plurality of different wavelength components, and that generates a terahertz wave by difference frequency generation based on the incident excitation light;
- and
- a plurality of detectors that detect each of terahertz waves generated in a plurality of directions from the nonlinear optical crystal.
