Abstract

Various electro-optic nonlinear organic crystals have been recently developed and successfully used as very efficient materials for the generation and detection of broadband terahertz (THz) waves due to their large second-order optical nonlinearities and excellent phase matching characteristics. In the present talk, some of newly developed highly nonlinear organic crystals, which can be applied for efficient ultra-broadband THz wave generation up to ~10 THz by near-infrared pumping, are introduced. Additionally, two approaches for suppressing phonon-mode absorption, leading to strong modulations of the THz spectra generated in most organic crystals, are discussed.
