Abstract

We report the measurement of optically rectified terahertz (THz) wave power relative to the optical excitation area. Rectified THz wave power reaches its maximum when radius r of the optical excitation area is comparable to the center wavelength of the rectified THz radiation. When r is smaller than the center wavelength of the rectified THz radiation, an r2 relationship is demonstrated. A model based on optical rectification and Bethe’s diffraction theory is used to describe this relationship.
