Paper Abstract

A couple of decades ago, the efficient and wide tunable THz wave generation had been reported by a group of Stanford Univ.1-3 based on both parametric and Raman effects. Although the interaction was highly efficient, most of the generated THz wave was absorbed or totally reflected inside the crystal due to a large absorption coefficient, as well as large refractive index (≈5.2 at THz range). They used a crystal one of whose corner was cut and polished at the proper angle to allow the signal radiation to emerge approximately normal to the exit surface.
