Abstract
To provide a monochromatic wavelength variable terahertz wave generation/detection system that has high detection sensitivity at room temperature and that can quickly operate at the same time, excitation light of monochromatic wavelength generated from one excitation light source is inputted to a wavelength variable terahertz wave source and a nonlinear light conversion terahertz wave detector through an excitation light phase control optical system shown below. The excitation light phase control optical system includes, on a light path of the excitation light, an optical element capable of simultaneously changing an incidence angle of the excitation light to a generation point of a terahertz wave in the wavelength variable terahertz wave source and an incidence angle of the excitation light to an incidence point of the terahertz wave in the nonlinear light conversion terahertz wave detector to set both the generation point and the incidence point at the same time on the focal points in a confocal optical system.
