Abstract
We demonstrate a direct measurement for parametric gain characterization of MgO:LiNbO3 crystal in injection-seeded terahertz (THz)-wave parametric generation pumped by 0.59-ns microchip Nd:YAG laser. We experimentally determined the gain coefficient and threshold length by measuring THz-wave output as a function of crystal length.
